"Make Checks Payable To" on invoice

How do I add the line “Make checks payable to X” to the invoice?

The name of the project is “Foo”. The name on the bank account is “Bar”. All payments need to be made to “Bar” (or I can’t cash them).

I’m assuming there’s an easy way to do this, but I can’t seem to find it. Help?
