I don't think this is supported.

Depending on how your "master" process works and communicates with it's
10 processes, you may want to consider splitting your service out into
separate systemd units. They can all be dependant on each other or,
depending on your IPC mechanisms, you can use socket or bus activation.
This then lets you have separate systemd units for each and apply
whatever accounting and restrictions you may wish on each.
