Scheduling Emailes

I would love to see a feature added where I can schedule invoices to get emailed at a later time as opposed to instantly. Reason being, I work on my invoices at hours other than the operations of my factoring company. So I create my invoice but have to come back at a later time just to send them out. If I could just schedule the invoices to get emailed at 10am the next morning that would be ideal.
