Problem: On occasions, certificates need to be signed by more than one person/institution. When these are not related to you, storing their digital signature may raise concerns and, depending on the applicable regulations, may be legally problematic. Request: Make it possible for "external" signatures to be added to a template. Example of how could it work: Template is designed, 3rd party signature component is placed on it. The component requires an email. Somewhere in UI a method to send an invite to that email is available. Upon activating it, the 3rd party receives an invitation to upload their signature. The signature is stored TEMPORARILY and indicated as Ready in the template. When the certificates are generated, all involved signatures are embedded. When all certificates are done, the 3rd party signature is deleted and a notification is sent to the 3rd party.
