Box Sign needs repeatable custom form fields (e.g. the signer fills out the custom field once, and then the field will generate the signer's input multiple times across the document. This is an extraordinarily basic function that most other signing services like Adobe Sign, DocuSign, and DropBox sign already have, and now that we've discovered Box doesn't have it, we're being forced to go to a third-party company and pay more money for what should be a basic function.
