Summary

Has anyone found a way to display attachments to External training?

We have a vendor that does some training for our people and provides a certificate.  I am able to build out the external training and add users and even attach documents to the user.   Thus I am able to tie their certificate to the user for that session/course. 

 

The real question is,  Has anyone found a way to display to the user the attachments that were tied to them in the external training?   I would love to see the system tag documents as certificates and then have a widget that shows all of the persons certificates be it form the learn system or external.
