Two different name on a button depending on the button state (T/F)

[GAP]

Hi there, a simple question...
I use a boolean OK button with mechanical action property : switch when pressed. I just want to have two different boolean text name in the two state mode. I.e. : 'A' when true & 'B' when false. When I change the name in the true true state, it change in the false state too. I don't want that ! I know it is possible to do that with the classical boolean button, but this is not my way... Thanks a lot.

goto customize
in the controleditor
right mouse click
almost bottomline
select multiple text strings
change the toplevel OK in A and it wil switch between A and OK
