you can specify the mc on the command-line for backup node, but, all of your data gets rebound tot that MC, including all of the fulls.
You might tinker with using different node names for fulls and diffs, of make extra fulls for the basis of the diffs complementary to the fulls you want to retain for longer, using again separate node names. all in all, NDMP is an awful mess. The industry could come up with a much better solution, but of course both EMC and NetApp prefer you to buying they filer to filer mirroring, snapshots and what not licenses and hardware to make backups over any tape solution that makes them no money at all.....
