[App_rpt-users] changing PL on the fly

is there any way to change the PL values on the run, or does it require a full restart, since it's not a rpt function as much as it is in the USB module? Just taking my nuclear option a bit further and actually have scripts to do so based on a function call (I put them in /etc/asterisk/scripts/lidon.sh and lidoff.sh), but right now, the script does an asterisk -rx "restart now" (reload just didn't read the usbradio.conf file,) Would like it to be a bit less 'nuclear' than aggravating my upstream hub sysop and other users who may be listening... Gentle direction appreciated... BB
