Currently from within PA in the detailed view, if you select some files in the file explorer you only get the right click menu if you right click above their name, if you do it within the selection but out of their names you get a menu to customize the view instead.
I think it's best to provide the right click menu throughout the line, or at least throughout the "Name" column.
I don't know if it's clear enough the description, so here is a screenshot: http://imgur.com/OYVeMKV
