Paginate arrays within variables?

Options
I can't use the "pagination" feature in the "output" tab because I'm pulling from multiple tables and then eventually merging. The resulting variable (object array) could have 0-n results, but I'd like to limit it to five or six. 

Is there a filter I can use to limit the results? I was looking at "range" but that seems to require I know the id of the objects, which I won't. Suggestions?

EDIT: I think "slice" is what I was looking for, yeah? Seems to do the trick...
