How to display pages by field in admin page list if fieldtype is "Page"?

[valan]

I'm creating a db of objects - hidden pages (cars) within PW. Perhaps not good in terms of site performance, but anyway...

Car page has "foreign key" - vendor page in a form of a Page field select.

Admin cars page list displays these vendor pages IDs, and here is my problem - for readability/convenience I need to display content of some field (vendor_name) within that Page, not its ID. 

What can be done in such cases? May be there exists some approach for page-in-page selection and admin display of fields from that sub-page?

You can just use subfields on page references. For example to get the title it would be something like this:

pagefieldname.title

wow! super! it works!

where these pieces of wisdom can be found on the site? I'll be happy to read document like "PW admin guide"... 

Thanks a lot!
