Percentage to Money Pot

It would be really great if it was possible to setup a money pot / savings pot that could automatically move a set percentage to itself on all incoming payments.

An example is if I use a specific account for all my freelance self employed money to be paid in to, each time I get a payment I can set that 20% automatically moves into the savings pot which is put aside for my tax bill.
