I had the same question
a while back and the solution I came to (after feedback from people here) was to go with the following clarification:
Only one Automatic Action may be done per Scene (or per leg of a Journey).
I know this issue has come up numerous times before on this forum as well, for instance
here.

I think it dramatically removes and reduces the tension to have them invoking a Trait over and over again. It also could give auto successes in scenes that otherwise should be dramatic. For instance, in our last game the PCs were shaking in their boots when they first met the dragon Raenar. Due to their being a really inexperienced newcomer in the party, their Tolerance was an amazingly low 1!

I allowed the Woodsman spokesperson to invoke True-hearted a single time, but after that the group needed to roll.
