Yes I think it is possible. It iis not clear if you are working from Excel or Word. However, look up INCLUDETEXT for Word.

Say you are working in Excel (as in you generate the Word document from Excel). You get the date from whatever input in Excel. Using some sort of logic, e.g.

January 31, 2013 means use the Q1 - 2013 word document

if the text in the Q1 - 2013 word document is bookmarked, you can use INCLUDETEXT to insert that bookmarked text into any document you like.
