Bill...
Let me take a crack at this. I think I understand what you are trying to do. When I was using the PSR 2000 I had a similar dilemna.

First...so you don't lose all the stuff you have in USER, copy it all to a floppy.

Then delete your USER file completely.

Now...load into the USER file the styles or other data you need that are on the floppies that have your "original" stuff.

If you already have the registrations you need on a floppy, they will link to the styles in your USER file. If they are on more than one floppy, consolidate them onto one floppy so you don't have to keep changing disks.

If you are going to do a "set" or whole gig of originals, this will do the job.

Now, here is the downside...but it is workable:
When you want to go back to the original data you had in USER, you will have to do this process in reverse...deleting the files from USER for your originals and reloading those that you saved on the first floppy.

The process takes a couple of minutes to do it, but it can be done on a short break.

That is how I was doing it before I got the PSR 3000.

On the 3K, all of this is unecessary because you can store just about everything you will ever need using a USB storage device such as a thumbdrive or on the SmartCard.

If you have any registrations that link to external style files, you just have to be sure you have them in the USER area. The 3K has more memory in USER than the 2K...but it is no infinite.

Hope this helps.
