Control timers w/ directives

Would it be possible to enable and disable timers through directives? I know there's a command to create timers, but what about having a directive that can control existing timers. Enable or disable for example $[timer name enable/disable platform]

Name = name of the timer (required)

enable/disable = this would... y'know, turn the timer on or off on a platform. (required)

platform = specify which platform. Optional. If it's blank, it would be the platform it came from. Maybe have all, to disable/enable on all platforms.

This would make things alittle more easier to control when making a timed command. For example, I am trying to make a heist command which would progress over time. So I need this timer to be enabled making sure a variable is active (minimum every 5 minutes as per timers). But once the heist is over, I want this timer to be disabled automatically, thus runs the timer directive to disable the timer.
