Wow this look amazing, this is exactly what i had in mind thank you so much.
Just one more question i promise . Could it also be done so that there is still a manual filter present at all times on the cells?
I have added a manual filter that also filters other criteria (e.g. Code, Owner) but every time i click on a User button that filter disappears. Is it possible that both options "co-exist" i.e. so that on User click, all his projects are filtered as described in the posts above, but a manual filter is also present at all times for additional filtering options?
