Mamiya made a duel cable release. One press locks the mirror, a second press triggers the shutter. They show up on Ebay from time to time and are a little pricey.
I am certain that those were actually developed for the K/L Lenses on the RB. All K/L Lenses have two cable release sockets, one for opening, one for closing the shutter. You would screw both of the cables from the dual-cable release into the lens, trip the mirror by hand, wait, then open and close with the release. A lot better than having to close the shutter via the dial or the cocking lever which you had to do with the older non-c, NB, and C series lenses.
Well now I'm really confused, I don't use bulb exposure on my RZ, or haven't, and only used T a few times.
Apparently the Bulb option doesn't work in mine, the shutter doesn't stay open when I hold down the trigger on the cable, it immediately closes...
It does however stay open indefinitely when I use T mode, you just have to manually uncocking the T button when you want it to close.
I find this a bit counter productive as this causes slight camera shake when touching the lens, however on an exposure you would need time for, you are shooting for a LONG time so the millisecond of shake while releasing the T lever on the lens is probably not going to affect anything.
However, still trying to figure out why the bulb doesn't work at all...
Mystery... I even change lenses, same thing ... Hmm...
