Could use some help with regex (in funnel plugin), anyone?

The url’s are
(always https, always www, never trailing slash

Basically I would like the goal conversion to be any page visit on (not a specific category and item but any!)

One of the steps in funnel would be (any category)

Because there are many categories and items involved I can only do the with regex, shouldn’t be too difficult but I lack regex knowledge altogether:)

A bit of help would be much appreciated.
