You might take advantage of the dialogData property.
For instance, from a recent post:

put "OK" into tBtn1
put "Cancel" into tBtn2
put "Are we going to the cellar?" into tPrompt
set the dialogData to tBtn1 & cr & tBtn2 & cr & tPrompt
modal stack "MyAsnwer" -- this will trigger preOpenStack in MyAnwser:  
see below
if the dialogData then doSomething -- see btn scripts below that have  
changed the contents of the dialogData in the meantime :-)
etc.

on preOpenStack
   set the label of btn "OK" to line 1 of the dialogData
   set the label of btn "Cancel" to line 2 of the dialogData
   put line 3 of the dialogData into fld "Prompt"
   -- your dialog is now customized
   etc.

on mouseUp -- btn "Cancel"
   set the dialogData to false
   close this stack
end mouseUp

on mouseUp -- btn "OK"
   set the dialogData to true
   close this stack
end mouseUp

Hope this helps
