Um, the following procedure sort of worked, except that it revealed another bug:

  1. Select the 'asian pawn' in the piece table.
  2. Press the 'Duplicate' button above the table. A copy of the row for the asian pawn is created below it.
  3. Write the desired move fsW in the 'Betza move descriptor' text entry, and click the move of this second asian pawn in the table to alter its move in that of an 'across-the-river' pawn.
  4. Click the 'Morphing and confining' link. An empty 'morph board' will appear.
  5. Select the across-the-river pawn in the piece table.
  6. Click the squares on the first rank beyond the River, where you want pawns to promote.
  7. Click the move of the initial pawn in the piece table, to associate the morph board to it. The morph board disappears, and is replaced by the setup board.
  8. Select the initial pawn in the table.
  9. Click the squares where you want to place them in the initial setup
  10. Select the across-the-river pawn in the table
  11. Press the 'Add as absentee' button under the board, to make sure it will be included even though it is not in the initial setup.
  12. Place the other pieces.
  13. Press 'Start position' under the board.

This should now create the definition for the desired Diagram.

The newly discovered bug is that after step 7 you will discover that the Kings that were originally present on the board will have changed into queens. This is a consequence of duplicating the pawn in the table; the piece numbers of all pieces below it is incremented by 1 by this, so the code of the pieces that were on the board at that point will no longer correspond to the intended piece, but to the biece just above it in the table. The intention was that the morphs should be defined before any pieces are placed, but the King was placed automatically when you opened the page.

I did not noticed this before, because I only tried duplicating pieces that appeared in the table after the King, when I was testing. But now we are duplicating a pawn. The workaround is to simply select a king from the table, and place that on top of the queen when you set up the initial position.

Anyway, the proper procedure is to first duplicate all pieces you need multiple times. Then redefine the moves, names and piece IDs of pieces you are going to use, (in so far the values from the table are not what you want), using the text entries below the table, and clicking the move of the piece you want to asign these to. Then define all the morph boards, through the 'Morphing and confining' link, placing the pieces you want to morph to on the squares where this should happen, and holes on squares that should be inaccessible, and then assign the morph board to a piece by clicking the move of the latter.
