Best field type and control for selecting multiple pages

I'm building a page type which requires a field that allows the editor to select multiple pages of a particular type.

I was hoping I could present them with a similar dialogue to the 'Select Page' dialogue you find elsewhere in the Kentico UI (e.g. when selecting a related page on the Related Pages tab). Except that it should be possible to select multiple pages.

I'd like to restrict this dialogue to a specific starting point in the tree, and only allow selection of specific page types. Ideally I'd store the Guid IDs of the selected pages, but I guess integer IDs is OK.

Is there such a form control built into Kentico? Or, if I need to build my own, is there a way to re-use the standard Kentico tree navigation dialogue without having to write a lot of custom code?

UPDATE

I've just found Brenden's answer here which I think answers my question. I assume Uni Selector is the way to go?
