Hi All,
I was wondering if anyone knows if its possible to do nested component templates, or if there is plans to add it?
An example/use case is the geo object. Currently the geo object is a nested object of client, destination, host, observer, server, and source. Instead of having to define the same fields within each of the top level objects, I would like to just reference a component template called geo, for each of the top level objects.
This would make management far easier, like if I wanted to add a custom field to the geo object, instead of having to update it in 6 places, I could update it in 1, and the change would be propagated on index change.
