Schedule Repeat Meetings

The current options in Scheduling repeated meetings is not sufficient

I want to schedule a meeting that occurs on last working day of each month. Currently I don't have this option or constraints to make it happen. So I have to create a repeat meeting and modify each meeting date manually. After this work around, each meeting becomes a separate meeting invite. 

I request the following enhancement.

Schedule meetings from beginning or end of month by days 1,2,3..n with a constraint on selecting working day.

Thanks
