Is your feature request related to a problem? Please describe.
I would like to have a list of processes using my webcam. But now I only have an attribute per process, where the attribute name is the process name and the value on or off. But since I don't know the process using my webcam, I cannot interpret the list

Describe the solution you'd like
A separate attribute with a list of process names using the webcam

Describe alternatives you've considered
Tried to create a template entity, but still I have the issue of not knowing what to search for
