Link to drawing custom properties

Hello everyone,

As an example:

I have an assembly with 2 parts inside.

Each part has it's own drawing and each one of those drawings have a custom property (attention, custom property is on the drawing, not the part).

I want to add a BOM table into the main assembly drawing that, for each part, will fetch the respective drawing custom property (into a column).

Any smart way to do it without macros?

For custom properties on parts this is quite simple, but for drawings...

Thank you for any help you can provide

Regards
