Fast formula to trigger two different rejection notifications to candidates

Summary:

We have a requirement wherein we need to send two different sets of rejection notifications to the candidates, One scenario would be when the candidates are moved to rejected state at different phases and another when the positions are cancelled and the rejection notification goes out to them?

Can this be achieved via Fast formula or Conditions to trigger two different rejection notifications to candidates based on two different scenarios that can coexist?

Right now if we attach both the notifications in the rejection state then both the rejections emails will trigger to the candidates , other option is to switch off one rejection notification to trigger another notification i.e only position cancellation notification.
