BICC datastore filtering and columns specific per offering

Summary:

When in BICC I create an offering I can select multiple data stores to extract from. If I make an adjustment to this data store by filtering for example only active records and some specific colums this data store is marked as Customized.

Offering 1: all active supplier sites who are marked for purchasing with the column address, communication method and email address

Offering 2: all active suppliers sites who are marked for pay with the column address, payment term and currecy

What I see is that in offering to I select the same data store with the already made customization for offering 1. But the data dumps are for 2 different purposes and I don't want to sent all the details to both parties. Is there a way to do this differently?
