Changing functionality of creating transactions from target group

Hi Forum,

In Segmentation,

You can go to a target group and create Business Transactions from it (for each BP in target group a transaction will be created).

How can we interfere with this standard functionality ?

Our needs: For BPs with specific characteristics we need to create new transactions whereas for others we need to add the BP as a partner in exiting transaction.

How the standard functionality can been enhanced ?

Thanks,

   I'll appreciate your help.
