There's a feature I used a lot with BlueBeam that allows you to create a "Stamp" and can use a simple code (I think it was "&Date" and "&DateTime" or something) to have it fill in the date or date/time automatically when you placed the stamp. You could create it in BlueBeam but the tools were limited, or you could import images to make it. Below is the example of the one I use currently. They also had basic pre-made template stapes like "Reviewed" with the date, or "Approved" etc. It's a nice feature. zzTakeOff has images so I can use the below image and just overlay the date on it manually that way, but a stamp feature would be nice.

Hey Dylan! Thanks for the feature request. Stamps are a planned feature. 🙂
