Inbox filtering options on read updates

I would like to able to view all updates of ProCan and filter by board. Currently I can only filter by board on updates I haven’t as yet read. I would use this to gather update information for reports ahead of meetings. Currently I have to try and recall information updates over the past two weeks or scroll through every single update when all I am interested in is one specific board. Is there a way to do this now?

Thanks
Alexis
