is it possible to force is_product to TRUE according to file extension into Synergy CM ?

into Synergy CM, is_product allows managing compilation products for example. but when you create elements (particularly when there are a lot of object files), you must tag each file individually.

is there a way to force this attribute at object creation ?

Moreocer, is there some litterature on is_product management (I found nothing or nerly nothing on IBM web site)

Thanks
