Allow Ring My Phone to be turned on/off by user with presence monitoring

Currently, if a user monitors multiple user's presence, there is only an option to turn on/off "ring my phone" for all users. It would be helpful to allow that setting to be turned on/off by monitored user. This would allow a user to see the status of users on their physical phone, but not have the phone ring for everyone they want to monitor status.

So, I would want to have 10 users where I monitor presence, but only 5 of them I want their line to ring when their phone rings.
