Question about IFS SAV and RST commands

Hello, all:

With SAVOBJ and RSTOBJ, I can specify the RSTLIB parameter on the RSTOBJ
command to designate a different library than was specified on the SAVLIB
parameter on the corresponding SAVOBJ command, for the library where I want
the object to be restored into.

But, suppose I have a stream file in the IFS that I want to restore into a
different directory than it was originally saved from?  ... Perhaps on a
different machine, where the directory tree may be different?  I can see no
way to do this with the existing SAV and RST commands. -- Am I missing
something here, or is this a known design limitation?

Thanks,
