Linking Body Text to 2 outline numbered lists

[justinepef]

I need to have 2 heading hierarchies available in the same template, and I've set these up with 2 lists in Outline Numbering.

1
1.1
1.1.1

A


A1
A1.1
A1.1.1

My issue is I'd like both hierarchies to be followed by the same Body Text style, which is formatted with alpha referencing (a, b, c). This referencing needs to automatically restart after each heading. (I can't rely on users to do it manually.)

I'm pretty sure I can't link the same style to 2 different lists, so is there any way to achieve this?

I'm using Word for Mac 2011 but have access to various Windows versions as well.

Many thanks.
