Yes it is very much possible.The broadcasting settings which you create gets stored in the table
RSRD_SETT_NODE_A
You should create one test broadcast setting by giving proper technical name through RSRT and then check if you can find the same in the mentioned table or not.
If you have the entry there then you can update the table based on your logic through custom program.
For more information on the same refer the below document.
