Templates that create multiple services on active checks

Hi,
as I was trying to figure out how to solve my own problems that I had with check_mk (this here Single active check that generates multiple services) I thought it would be nice to have some sort of template engine / autodiscovery for active checks.

To stick with my problem I stay with the Webmonitoring with full chain.

We provide managed hosting and would love to template the webmonitoring. I add an URI somewhere and the autodiscovery creates a couple of services that get monitored all togehter as active checks.
