Auto Tagging to existing (recurring) invoice

Hi,
I know this is not possible but I just wanted to make it a Feature Request.
i.e. Money comes in, it is autotagged to the most recent invoice on the client account for that amount.
Thanks

I tripple that motion.
Seems mad this is not a feature as it would be the most useful next step after auto sending recurring invoices.
my account are in a mess because of this, have turned off autotagging entirely as it creates and then logs a double payment.
Number one please !
