Out of curiosity - has anyone found a way to do a round-robin or random selection from a list. Example for assignments if I have a filtered list to randomly pick different available names?

Sounds scriptable. Load all the IDs of active elements, shuffle them, pick one, setValue.

Yeah I'm sure it is scriptable was hoping I could get deep with Workflow and Formula.

Interesting challenge 🤔... you can use Saved Searches in WF... I wonder if we can get a random element in a SS and use it in the WF
