Can you update the field name "Original Estimate"?

We are trying to distinguish between Original Estimate and Estimate, where estimate is the operating estimate and original was the first estimate.

Hi @sarah.ferrara

a pure rename of "Original Estimate" is not possible to my best knowledge - it is a system field.
Please let us know if it was what you were asking or if something is left unclear.
