HCM Extracts - Import an extract after changes

Summary:

I would like to Import an existing extract after changes to the extract

Content (required):

Currently when there's a change to the existing extract, I use the 'Advance Edit' option to make the changes.This works well when the changes are small.

When there's a lot of changes to an extract, is there a way to import the extract with the same name? (Like how the BIP reports are imported)

If there's no such option, how do you guys migrate big changes?
