Remove multiple memberships from a AD group?

I got a request from customer that "persons on this list should be removed from this AD group". First I thought that it's a simple task, but then I realized that I don't have a clue how I can delete memberships using DataImport -tool. And I'm not sure what will happen if I just delete those lines from ADSAccountInADSGroup -table, will it launch the remove process or not.

So what is the best way to remove number of memberships based on some list from AD group, using OneIdentity v. 8.1.2?
