Potential Feature Request?

As someone who has had to, twice this year, go through my RP list and manually add each individual person that I have an RP with as BCC's to a PM so I can tell them about the new fun and creative way that my life is potentially about to suck in the near to immediate future,-- it'd be really nice if there was some way to automate this process so that I could say... add a pre-generated list of names to a PM or at least save a copy of said BCC's after doing it once.. you can't even really reply all at the moment.
I have no idea if this is a realistic request, or something that I could actually do, but it's apparently one that I at least need. I'm sure others would find it useful too!
Sofia Grace, also, has supported this potential suggestion!

Either way, thank you!
