Global variables for links behind reverse proxy

Hey

Is there a way to use a global variables for links (a tags) so they can then be used inside my dashboards. Im running grafana behind a reverse proxy. in custum.ini I have my root_url=“mysite.com/grafana” and i want to use that root_url variable inside my grafana dashboards, something like… a href="${root_url}/dashboard1"… Is that possible ?

Best R.
