Print multiple documents to .pdf - wait for next page

When I print a word document to .pdf in Acrobat I often want

to have the document include pages from different documents.

Often I will want to add a supplement, for example, or combine

different pieces into a single presentation.

I can't find a way to have Adobe "wait" for the next parts of the

new .pdf document; instead, it will not print until you give it a

name and a "save-as place," and when you do it automatically

closes.

So to make a .pdf from several different documents, you have to "print" them all

to .pdf separately and then try to combine them.

I am looking for a way to add more pages to the document before

Acrobat names and closes it.
