Can't you use two commands?

There is a mount retention period.  If it is set to 60 minutes, the tape is
left in the drive until either another tape is required, or 60 minutes has
elapsed.

It would be nice to have a feature to restore all filespaces at once, but I do
appreciate that if I say restore "/*" it only  restores the root filesystem,
and not everything.  I suppose you could create a scrpt that will take the
output from "dsmc q filespace", and parse it, and fire off a dsmc restore for
each filesystem.
