We are working on this--the way it will work is that if on
the generation options screen you select a default field
type of passthrough (new option), all of the portions of
the screen you didn't touch will be <TEAREA> tags,
surrounding the fields that you did touch.
There may be formatting issues with this approach in
columnar layouts, but in many cases it should work OK--our
earlier DevCenter wizards actually worked like that, and
now we are working on merging the old and the new.
One caution is that a screen containing passthrough tags is
not usable for a create or update workflow--only inquiry,
since the data in the screen cannot be stored properly or
identified as fields.
Will let you know when the new functionality is available.
