Original Estimate in Board Settings and Issue visibility

[Nico]

Hi all, I read many threads about Original Estimate (Time Tracking field) and I think I arrived to a "configuration deadlock"

What I need --> 1) to have the Original Estimate only available and visible in Sub-Tasks (not in User Storied, nor in Epics) and 2) configure the Board Estimations, Estimation Statistic set to "Original Time Estimate" and Time Tracking to "Remaining Estimate and Time Spent"

And I have these scenarios:

A) I Hide TimeTracking field from every screen and Issue and the Board Estimation configured as point number 2) described above --> With these configuration, I still see the Original Estimate in User Stories (against What I need, point number 1)

B) I configure the Board Estimation by Story Points and time Tracking to "Remaining Estimate and Time Spent" and keep hiding TimeTracking field from every screen --> With this configuration I get What I need in point number 1 but against my board prefered configuration to track the sprint

I hope to be clear and specific, and get some help
