Doesn't disklabel translates da1 to /dev/rda1c? The man page seems
to indiate that it does:
Disk device name
All disklabel forms require a disk device name, which should always be
the raw "complete" (or "c") partition, for example /dev/rda0c. disklabel
understands the abbreviation da0, which it converts internally to
/dev/rda0c.

I was looking for an option to do this from disklabel but I didn't
see one. Wouldn't this be a nice feature to have on FreeBSD?
Well I tried this and I get the same results as before :(
