Make MTR Check usable for Piggyback

Using the MTR Plugin on the checkmk server or a dedicated linux server is nice. But for better overview related for e.g. webservices hosted somewhere outside the own infrastructure it would be nice to have the possibility to define a "Piggyback target host" per destination in the Agent ruleset.
Example:
There is a webservice host named: checkmk.com
There are HTTP/S & Certificate Checks visible on that host

For MTR monitoring it would give a better overview to have the Check also directly below the checkmk.com host instead on the checkmk server or a third linux box. As it is not an active check, the only possibilty to achieve this, would be piggyback in my opinion.
