Is there a DRM command-line way to merge catalogs into a single deployment?

Hello all,

We have a large deployment of single-servers out in the wild r330s, r420s, r720s, etc -- of various versions of machines with various hardware, depending on what people were able to procure.

Thusfar, we have had DRM log in to each machine (with --deployment-type=idrac) and create a unique catalog per-machine.  We now have a hundred catalogs that we have to re-extract, This is dumb.

So when running updates via the idracs, we have catalog names like SITE_1.0N_Catalog.xml that we have to script out (since a newer machine may only have changed twice and be at 1.02, but a machine that's been around longer might be at 1.07)

Is there any way to say "Just build a single catalog.xml with all the things in all these catalogs", and actually call it Catalog.xml with no prefix or version number (so we can accept the defaults in the idrac web UI)?

Failing that, I *could* start over and create a single repo with every possible hardware and component type, but I would have to periodically update that, say, when the R450 or R460 came out.
