Can I change the master during soft proofing?

[J Isner]

When I do soft proofing, I display the master in Before and the proof virtual copy in After.  Occasionally I'll be in the middle of making changes to the proof copy when I notice a problem in the master, for example: a dust spot.  I could fix the problem in the proof copy, but it really should be fixed in the master.

How I currently handle this:  I go back to the master, make the change, create a NEW proof copy, sync changes from the old proof copy to the new proof copy, and delete the old proof copy.  This is awkward and error-prone.  Is there an easier/better way to do what I want?

Have you tried selecting both the Master and Proof copy in the filmstrip of the Develop module, switching AutoSync 'on', and then doing a retouch?

This will apply any adjustment to both.

That's the solution, thanks!  But in order for it to work, you must make the changes to the master in Loupe view with soft proofing turned off (otherwise, Lightroom will ask if you want to create a proof copy) and the master most-selected.  Autosync doesn't seem to work in Before/After view.  Then, with the virtual copy most-selected, return to the print module.
