BBP_WF_LIST to fire on conditon

Hi.

We are using SRM 7.1 - the Badi BBP_WF_LIST is being used to filter the carts in SoCo based on some custom logic. however we want the custom filtering to trigger only for the 1st time when the list gets displayed. i.e. at the very 1st time when the buyer comes in the Sourcing transaction. Every other time when the buyer uses the "Search" button or enters some fields in any of the selection criteria for the SoCo, we dont want this filtering logic of the BAdi to fire.

Can this be achieved?

Thanks.
