Modify the value of a Hex Row

Hello everybody, i would like to ask you if you know how to set a hex row one number lower from what it is.

Example :
Hex Grid Numbered with Letters as columns and Numbers as rows.

A2 - B2 - C2
A3 - B3 - C3

I need to tell Vassal somehow that when he is reporting the movement of a piece in a hex, he should give me the hex value but with the row number reduced by 1.

Example in game :
“Piece moved from A2 to B2”

I would like to read : “Piece moved from A1 to B1”

Even if the hex id is not the right one displayed, i don’t care.

Is there a way to do this or i have to manually redo the entire game map?

Thanks alot to everyone!

Why do you want to show the hexes as 1 less that they actually are?

Is it because the hexes reported by Vassal are out of sync by 1with what is printed on the board?

In that case, it will be vastly easier to just edit the Hex Grid Numbering component and reduce either the ‘Starting number in horizontal’ or ‘Starting number in vertical’ by 1. It is OK if these number go negative.
