Can I change my Template’s document, without losing the fields?
You most certainly can! A lot of the times you’ll have a document that needs updating with new terms and it can be a right pain to have to add all those fields again, so Signable has a feature that will help you out here:

Head to ‘Templates’ on the left.

Click onto the template you’d like to change the document of and click ‘Replace Template’.

Click into the box and select your document and then you’re all done!
