Unable to Edit "source_request" in the OOB UI Builder

[Apurva Tatekar]

Hello Everyone

We have a requirement from the client to  ADD new "On Order" tab next to "Vendor Purchase" tab in HAM Workspace.

I tried to modify it through the UI Builder --> Experiences --> Hardware Asset Workspace --> Source Request Default
But, getting the below message. 

Read-only. The page definition and variant are in different application scopes.

Is there any possible way to achieve this requirement?
Thanks in Advance!

Please duplicate the variant and give it a lower order for your variant to take effect.  As some of the OOB pages/variants remain as readonly you cant make changes.
