Set max run time for AVD in autoscale settings

Wondering if we could get a setting in autoscale to set a max run time for AVDs. Frequently, we find that some boxes end up running 4 or 5 days without a reboot. Somehow, these boxes end up with users who work longer days, and they end up being the last few boxes remaining in the pool, so they never reboot at night. A setting in autoscale to deactivate boxes once they have been running for X number of days would be helpful to prevent the long run times and the issues that can cause.
