Is there any way to coax an APX7k (running R8.05) to enable the "SoftID" feature for some personalities (or, failing that, for some Astro systems) but not for others? In the CPS it seems to be an all-or-nothing radiowide feature, but perhaps I'm missing some trick.

In particular, I want to send the radio's softID with every keyup on some P25 channels but not on others (where I want to send just the vanilla numeric unit ID). Can it be done?

Thanks
