Allow to schedule a recurring maintenance window for only a specific day in a month

I would like to have the possibility to schedule a maintenance window for only one specific day in a month.

For example:
I’d like to be able to set the 2nd Monday of the month, between midnight and 6 in the morning as a recurring maintenance window for one or more devices.

Currently this is not possible, I would need to set the maint. window on every monday for that timeframe in order to have it covered.

I would find this helpful as well. Especially for Windows devices after a ‘patch tuesday’. We typically due the third Sunday of the month at for these sorts of updates. I can schedule every Sunday but that leaves a big window open for something to happen on days where no updates take place.
