first of all merry christmas and a happy new year

i just have a small question.
I am running pi-star 4.1.3 and want to change the talkgroup from my command line.
i already found dropping tg via the BM api .. but not to change the dynamic group from the command line, not from my radio
again this is NOT the static but the DYNAMIC tg change
or...
is there a way to send some data to an udp port , just like the ysf reflectors ???
for example if you want to change the YSFReflector from the command line we can use:
echo -n "LinkYSF21080" |nc -u 127.0.0.1 6073 -w 2
is there such a way for the dmr talkgroups ???
i hope someone can help me with this
Many thanks in advance
