JQL for getting tickets that were either assigned to me or any of my team members in the past?

[Tayyab Bashir]

Hi, 
I want to get JQL for getting tickets that were assigned to me or any of my team member, either in the past or at current point.

I'm using the following filter which gives me tickets that were assigned to me in the past and now:

Project = "XYZ" and (assignee was tbas)

but I want to add my team members in there as well. And I think the assignee was operation doesn't support multiple values? 
Is there any way I could list multiple values other than adding them in separate assignee clauses?

Simple JQL.
Project = XYZ and assignee was in (abc, xyz)

assignee in membersof("groupname")
