extension integration - sort counters with base module

I’m building a base module and several extensions in 3.2.17

All the components are working fine, but any pieces I put in the extension are getting listed at the end of the counter list. Is there a way to get them to show up in-line with the counters from the base module?

As a simple example:

in the base module, I have counters in a Game Piece Scrollable List named:
Able
Baker
Charlie
Gamma

and in the extension, I have:
Bravo
Delta
Echo

So when I load the base module and the extension they get put in my Scrollable list in the following order:
Able
Baker
Charlie
Gamma
Bravo
Delta
Echo

But what I want to have is:
Able
Baker
Bravo
Charlie
Delta
Echo
Gamma

I tried putting blank entries in the base module for the extension entries (trying to follow the example under the Extension Integration in the manual), but it didn’t use them.

I guess this should really be in the Game Modules area. I’ll ask over there.

Sorry.
