SDT On Datasource/EventSource Groups

We've created a lot of custom groups to put certain types of eventsources and datasources that are all related into one area (e.g. Customized Logs). However, we cannot set a SDT for the entire group, but instead, we have to put it on each individual device.

This severely limits the capabilities and usefuleness of creating datasource groups. It would be extremely helpful to allow the capability of SDT at the group level.
