You can assign another category with the 'mtlib' cmd after checking in
and assign to server as You need them...

There is a redbook: Guide to sharing and partitioning ibm atl
on this stuff, a description of the predefined categories is in the
appendix.

We are using 'checkin' and 'label' cmds only with volume ranges...
