Something I love from Shadowrun 4e was having multiple drones work together. How about we bring that back for 5e? To be fair, I think you should be able to slave a drone to another drone, but it should take a program slot on your RCC. For general rules on programs, see page p243 in the main Shadowrun book.
Master/Slave: Choose one drone you control as a master, and choose a second drone that you control to be the slave. When you issue a command to the master, the slave will also undertake the same command.
