Hello.
Yes eaDocX will print information about related elements which can be located anywhere in your model.
Here is a link to info which describes various ways in which you can structure your documents using eaDocX:
https://store.eadocx.com/help/index.html?structuring-your-document.htm

There is information about printing related elements (and the relationships to those elements) in the help here: https://store.eadocx.com/help/index.html?related_elements.htm
And in more detail here: https://store.eadocx.com/help/index.html?related-element-data.htm
(there are also sub-pages which go into even more detail)

In addition you can print multi-hop relationship data –

(PS the help says that this is an experimental feature but that message is old and will be removed shortly – multi-hop is now an established part of the core eaDocX function)

Best regards
