No a sub-report produces information which gets printed inside the host report and is not page aware. Now, tricky to say, but usually sub-reports are quite limited in length, in what they produce, Saying this I have the feeling you have a lengthly sub-report (in mind). Note that when you have in mind to have a kind of empty host report and the sub-reports are in fact main reports you better off with producing multiple output (PDF) files and combine them with a PDF concatenator tool.
