if you are on the group / members tab, the "Actions" drop down shouldfor each membership should have "attribute assignments" and it should link to the same screen as the member screen membership attribute assignments: https://grouper.apps.upenn.edu/grouper/grouperUi/app/UiV2Main.index?operation=UiV2MembershipAttributeAssignment.viewAttributeAssignments&groupId=dbfa18c3-a025-47b6-a9a0-be5ac02e8270&subjectId=10021368&sourceId=pennperson
 
for that drop down you need read_attr or admin or update_attr
 
 
on the group screen, under "more actions" add a "Membership attribute assignments" button which looks like the "Attribute assignments" screen but with group column, and entity column, and a column that says "assignment type" which is "direct" or "any membership". new screen.
 
when assigning a membership attribute from the subject add a group combobox (which defaults to current group)
