How to add a 'Categories' drop-down box to the 'Manage active listings' page

[popch3]

Does anyone know if it's possible to add a 'Categories' drop-down box to the 'Manage active listings' page and the 'Drafts' page, like the 'Manage unsold listings' page has?

I've tried 'Customize table', but I don't see anywhere to add a 'Categories' drop-down box.

Is this possible? Anyone know how to do it?

Thanks!
