Allow filtering for multiple (unlinked) projects at once

[Aron-11]

Dear GitHub Club,

I would like to have an overview of up to 4 projects at the same time on our wonderful and lovely dashboard.

To get this done is highly appreciated by a lab tech on the other side of the dashboard..

Thanks for forcing me to a github account, that I just will use ones in my life time 🗡️

Best
Franzie

What this means is essentially a 'OR' parameter to filtering should be also added. Rather only than additive ANDs when doing the project filtering.
