Fernando is right. I did not have a look to the source code but I think when
you attach a volume to rsector, the pointer representing the volume is
transmitted to the rsector, so when you attach two volumes to rsector, only
the second will be attached to.
An alternative to your problem (if you don't use module and submodule for
example) is to define a volume representing the module to the half of your
rsector and to repeat it twice, so you can have two 'rsector' except that
their names are 'module' !

If we don't answer to your question, could you describe more precisely what
do you want to do ? Because I think that it is probably feasible.

Cheers,
Simon
