Include greeting in signature

Just started to test Mailspring and I’m very positive overall. However, I’m really missing the ability to add a greeting on top of my signature. I don’t think templates should be necessary. All mail clients I have used earlier had the ability to add “Best regard, [your name]” to the bottom of all new messages.

The signature editor is a very nice idea, but is it in the way of achieving this easily?

Best regards,
