How to change CoA Future 1 segment name?

Hi,

We are a few years post-implementation. Our CoA was created with 2 spare segments for future use. We now need to start using our Future 1 segment and wish to rename it.

Can anyone advise on the step-by-step changes we need to make in Setup and Maintenance to achieve this?

I can see areas under Manage Chart of Accounts Configuration, Manage Chart of Accounts Structures, and Manage Chart of Accounts Structure Instances where it looks like we could make changes.

Our main focus is on making sure there is a meaningful name for end users whenever the segment appears in the UI and ideally for selection when creating reports in OTBI, SmartView, or in FDI.
