How do I use a theme package developed with Command in Architect 3

Environment details:

Sencha Cmd 4.0.2.67

Sencha Architect 3.0.2.1375

Framework ExtJS 4.2

Windows 7



Path to where I am today:

- Generated a workspace

- Generated a demo app to demonstrate a custom theme

- Generated a new package that inherits from the ext-theme-neptune.

- Modified the styles via the mechanisms provided in the sass directory of the new package.

- Build the demo app and successfully shows the theme being applied.

- I have brought Architect projects into the workspace.

- I can change the referenced theme and build those projects with Cmd to use the new theme.



Problem:

I can't figure out how to import the theme package into Sencha Architect. I've seen one post that mentions bringing in the output css as a resource, but that brings architect to it's knees, and doesn't seem correct. It seems like I should be able to bring in a theme just like Neptune and make available for applying as a theme.



I've spent several business days trying to figure this out. I can't find documentation or forum posts trying to achieve this. It seems like the closest thing to what I'm trying to do is to use a user extension. But when I manually zip up my package into a .aux file, Architect says that it is an invalid package (with no further details).



Desired Approaches:

- I'd like for Sencha Architect to see the package in my workspace and allow me to apply it as a theme to my apps.

- Or, if I have to import it, I'd like to see some documentation specifically on how to import a theme package created with Sencha Command into Architect.
