In short, give up on getting labels redone when recycling.
To do that is not recycling.
If you are absolutely dead keen on relabeling, delete the volumes
yourself, via script or otherwise. ignoring recycling. i.e. Do not
Recycle.
If it was me, I'd allow recycling and ignore the labels. Labels are
just labels and in my humble opinion, and your milage may vary, having
the date in the volume name is not useful to me. I can see the last
written date for a given volume by inspecting the output of 'list media'.
