Create automations based on estimate fields

What is the challenge?

I cannot create an automation when an estimate field is updated.

I have a tag that lets my dev lead know when a feature needs an initial estimate. When the initial estimate on a feature is updated, I'd like to remove the tag.

What is the impact?

Manual repetitive work to update my records.

Describe your idea

Add initial estimate and detailed estimate fields in the "select field" dropdown in automations.
