WSOA1: Mass assignment of customers to Assortment User

Hi All,

I have recently started working with IS-R and want to know the following.

I'm working on setting up of outbound pricat functionality for our wholesale customers.

With transaction WSOA1 I am able to manually assign customer numbers under "assortment users".

But this actvity is manual.

I want to know if there is a mass change transaction in IS-R or a way to assign multiple customers to an assortment?

Many Thanks
