Not easily, but using pre scripts and modifying your autoyast file you
could probably do it.  I have stuff to handle cases where if an existing
host is being rejumped and matches some validation (some basic
"security" features) and has valid partitions, then the autoyast file
has the <partitioning-advanced> bits and re-uses partitions, else it
uses regular <partitioning> logic and wipes/initializes the disk.

So, in theory, you could do a pre-script to look for existing
partitions, and if you see one (and I'd validate it by mounting any
visible partitions and looking for (a) specific file(s) to make sure it
is a rescue partition, unless it uses a different partition type, then
that's easy to check) and have the resulting xml written based on seeing
said valid rescue partition or not.

But I also do a lot of pre-processing of the xml in our current imaging
process.
