What is the desired functionality that you are missing?

When filtering by process instance state, I can only pick 1 option

I want to pick multiple options.

Which problem are you going to solve with this functionality?
R+V describes wanting to filter by unsuccessful process instances ("only use process instances that were cancelled or that have at least one open incident")

Additional Context:

1. "It would be useful for the enduser to have the possibilty to combine filter criteria with OR. The OR should combine all filters, not only variables."  (SUPPORT-8699) - this is resolved by OPT-4520
2. OR filters between the same filter types are sufficient for the customer - Asia
