I'm handling two type content, B referenced to A by "Entityreference prepopulate (create link) and Entityreference Autofill.
Then, users can see in the B add page some fields (disabled) that (they or someone else) has previously filled in content type A.

The problem is that if something needs to be changed in those fields, users must come back to the previous page, edit it and repeat the "add B node" task.
Since the referenced entity is on the page, is there a way to insert a link in the B edit-page (as link not as editable field) like "node / [node: referenced_field_entity] / edit" and target it "_blank"?

I tried different methods but still can not make it.

Does anyone have any suggestions?
