Continuing the discussion from External link on display:
I upgraded now to the last version (from 1.8.6), and I saw this feature implemented.
It’s not useful for what I suggested, because it only allows to replace the IP address with %s, while with teamviewer I don’t have it.
It could be a totally dedicated “title link” field, in which I could put the full URL I want to use.
EDIT: to better explain, a dedicated new field, in the display parameters, not the actual field in “General” which is valid for every display, not specific.
