You asked for "a way to start/stop timers on a specific entity without creating a bunch of different events".
As I understand it, Enable is just a switch that stops/starts the Timer clock. It has nothing to do with triggering events and does not require any events.
So if you set a timer to fire in 60 minutes, then after 10 minutes disable the timer, the timer should fire its event 50 minutes after it is enabled.
