Grouping by "Assigned To" + Filters in Task Pages

Hello!

I’m running into a formatting issue to see specific results in a custom page. The page is a tasks page meant to return the tasks of a specific list of artists, and have the results grouped by Artist.

The issue is, when there are multiple assignees on the task, and one of the artists is not in the filter list, they are given an individual group on the page, creating 1. duplicate results on the page 2. groups of tasks that belong to an artist not in our list.

My temporary solution is to not use grouping at all and use sorting instead, but visually, this is not ideal, and makes it harder to see the information required at a glance.

Let me know if this is clear and if there are any potential solutions,

Thank you!
