Hi,

RTC already does this, at least for the workflows themselves. Every time
you change the workflows and do a save RTC saves a copy of the project
area configuration. This is the Project Configuration Source XML data.
The workflow definition is stored in there. If you go to the source tab
you can open a mouse button two and say Show History it will show all of
the previous revisions that had been saved. You can then do a replace
with one of those previous revisions.

However, you need to be very very careful. This is a complete
replacement, which can be more than just the one workflow.

Instead you may want to do a compare with a previous version and just
merge in the changes you want.

This is not the graphical interface to the workflows. It is the XML
representation of the project area configuration (which is actually the
master). So you'll need to understand XML and the project area
configuration XML.
