Composite element templates
As an user I want to be able to create a template hierarchy (parent-child) all at once, so that I can easily create a hierarchy representing related assets. For example, create a motor, gearbox, compressor train with a single template that actually consists of (in this case) 3 templates.
I understand this would probably be a major change on how AF is built, but composition would be extremely helpful for designing AF Databases and models.

It should be part of PI AF's build-in feature, as everyone will think it should behave in this way naturally.
This is a requirement that I, and a number of other users, have identified as being very useful.
