Adding External Memo's on Shipments

Hello, 

When I email out a shipment, I want to be able to send customized Memo's to my customers providing them with instructions. 

I don't want to go every time to: Settings --> Print Form Set-Up --> Shipments each time to create a Custom External Memo. 

As an idea, can we have the ability to email Shipments with Customized External Memo's?
