cgroupsv2

I have a problem with cgoups. I want to limit network traffic of processes based on their process path, not pid. My problem is that some of those processes are not running and maybe they will run later. So I don't have any pid to add in cgroups. What should I do?

I have a problem adding cpu controller since command gives error : sudo echo "+cpu" >> cgroup.subtree_control bash: cgroup.subtree_control: Access Denied. Therefore, I have found a solution is that I have to move all realtime(RT) processes to root cgroup as explained in cgroupv2 documents...
