Binding email template macros

Hello,

I've created a set of new email templates that include both standard and custom macros sourced from macros in related objects. To share these templates with my colleagues, I’ve attached the email templates to my current package using an EmailTemplate data file. However, the custom macros within these templates aren't being included; my colleagues are seeing only the email template itself without the custom macros in their message templates.

When I attempt to bind the macros using an "EmailTemplateMacros" data file, I’m only given the option to include basic macros—none of the custom macros from pre-defined objects appear. Does anyone know how to properly bind these custom macros to the email templates so they appear for others?

Thank you!

n.b. some of the basic macros that I am able to join seem to be generic fields, not the fields I want to bind - see below...
