Adaptive search for Revenue Lines - can more opportunity fields be added?

Summary:

 Can more opportunity fields be added in Adaptive Search for Revenue Lines?

Content (required):

We have enabled Revenue Lines in Adaptive Search to use in Workspace.  There are 3 opportunity fields that can be added to the columns on the Revenue page.   Is it possible to have more Opportunity fields made available for selection to be dislpayed?  For instance, sales stage?

Please see attachments to further clarify where I am looking for the opportunity field(s) to be added.  'Revenue lines display.png' is where we would like the user to be able to select additional opportunity fields.

'Adaptive search config UI revenue lines.png'  is where I was looking to see if more fields could be added.
