Boards dynamic intake for tasks with multiple assignments

[CBuckwal]

I'm new to using boards and have started to set up one of the requested boards, using dynamic boards, and have run into an issue that I can't seem to figure out. One team asked for a board to show all their team member's assignments. Team members may be assigned team projects but could be assigned to projects outside of their team.

No matter what filters (shown below) I try, additional non-team members assigned to a task also show on the board if the task has more than one assigned user.

Simple filters-assignment using team members names

assignedToID=6305263c00b4c3cfcfeb0d90eff5b19d,63ac6a560023912f68dfec309f36f303
assignedToID_Mod=in
assignmentsUsersMM:homeTeamID=6638225d00bcfbf4b1b9d9ea44489d1e
assignmentsUsersMM:homeTeamID_Mod=in 

I know tasks with multiple assignments happen on reports too, but it doesn't really matter in the report. The team doesn't want to see non-team member task assignments showing on their team assignment board and don't want to have to filter the non-team members out. 

Is there a filter to accomplish this that I'm missing?

Thanks

I think I submitted a case once to Support and was told that this is pretty much the way it's intended to function and you can't filter those non-team people out in any way.

That's too bad. I thought that may be the case based on what I was finding when trying different filters.
