Is there a way to grant rights to a group members instead of set of users

Hello, 

Is there a way to grant the rights for some custom object to a group of users (security group or distribution list). I tried to create a grant right MPR that use the SET as requestors and that set have the group (security group) as manually added member.

But this doesn't seem to work, most probably due to the fact, that in the SET there is a group, so the group is authorized to perform the allowed action but not the group members. Is there any way to grant rights the members of group (of course without building much additional logic) ?

Thanks
