advanced find and N:N columns

Hi,

I'd like to obtain information using advanced find, but I don't know how to do it:

I need obtain information from different entities an filter that information, so I have two entities related with accounts: I have an entity called Brands that has a relation of N:N with accounts. I have another entity called Product Types that has a relation of N:N with account.

So I need to query accounts that accomplies some Brands and some Product Types and I use related option in advanced find, but I only could select columns from account entity. I need add columns from Brands and Product Types to know the names.

How can I do this?

Regards
