Hello Jira brain trust. How to require orig estimate at workflow transition?

Scott Thurston_22s9a2

I want to make it so when a developer transitions an issue to the "in-progress" status the system prompts with a screen that asks for the original estimate.  I made the status transition use a screen called "#### Estimate Screen".  But I can't seem to add the original estimate field to that screen.

Note: The field is on the full issue edit screen but not in the drop-down for the estimate screen. Note: using Jira Cloud.   

Any advice on why I don't see the ability to add original estimate to the transition screen or any self made screen for that matter?

Take a look at the Timetracking field. It's a combo of Original Estimate and Current Estimate fields
