"All Call" on Motorola GP360

Hi,

Apologies if this is the wrong forum but “it didn’t seem to fit anywhere else”

Based in the UK running a show using a bunch of old Motorola GP360’s where we need to be able to speak to individual users which is easy enough as we will allocate each a separate channel, however there will be occasions where we need to speak to all users on all channels simultaneously was wondering if this is possible on Motorola GP360s and how I would go about doing it?

Obviously it may/will need programming but before I shell out on that (money is tight!) wanted to check it is even possible and would a newbie be able to program it if needs be.

Thanks
