Automation - action if a multi-select field contains any value other than some specified values

[Julia Foden]

Hi

I have a multi-select field for Countries which has 245 option values. Approximately 30 of these countries are 'pre-approved'. So the automation needs to say

IF the Countries field contains any value(s) which are not 'pre-approved'

THEN do something (create an approval subtask)

I know I could do it by "If Countries contains any of <list 215 values>" but I think surely there must be a better way.

I have tried branching on each value in Countries and then doing various things but the problem, even with a re-fetch, is that the rule jumps ahead and doesn't wait for the branches to complete. I am attaching a screenshot of my most recent attempt, using a regex and then filling a random field and using that field to trigger the action.

Does anyone have any ideas on a different way of doing it because branching here seems a non-runner.

Thanks in advance!
