I'd like to have some tasks repeat on the first weekday of each month. Currently it looks like you can only repeat on the first specific day like a Monday. But I want to be able to repeat per some logic like: "Repeat this task on the first day of each month, unless that day is a weekend, and then repeat it on the first Monday."

Seems like there must be a lot of tasks like that. For me it's billing clients: when the 1st rolls around I want to add up hours and send out the bills so I can get paid! But if I put "1st Monday" it could be as late as the 6th before that rolls around.

Thanks.
