Add date function to Pay run automation - Auto Emails

Please can we get this added so we're able to send automated emails which are only needed at certain times of the month rather than each time a pay run is finalised?

For example, P30/P32's we only need to send nearer the end of the tax month and would not want these to be sent each time a pay run is finalised for clients which have Weekly/Fortnightly payrolls.

A function with a drop-down with a date to be sent each month would be really helpful in this case.
