Repeating Regions in Nested Templates - PROBLEM

Passing repeating regions along nested templates.

[shafaki]

How can I pass a repeating reagion accross nested templates in Dreamweaver?

<problem>
I have a main template T1 and a nested template T2 that I created from T1.

T1 has a repeating region. When I open T2, I am able to use the controls of the repeating region.

I have created a document from T2. In that document, I am unable any more to control the repeating region, the repeating region controls have disappeared.
</problem>

How can I let a repeating region in a parent template pass not only to its child template, but also to its 'grandchildren', that is to documents created from its child template?

Can this be done at all in Dreamweaver?
