Can I create my own email template collection?

I know I can add templates to the Default Notification Collection but I
think I may want to create collections for each driver.

I was able to create a new collection object (objectClass:
notfTemplateCollection) by copying the Default Notification Collection
object to the Security container using iManager. (I tried placing it in an
OU but iManager threw an error on that.) I then moved a template I was
working on to the new collection.

I can't seem to get Designer (2.0M1) to import the new collection. Nor can
I find an operation that will allow me to create a new collection.

Can this be done? Should it be done?
