Combining Word-docs based on a design in Excel

[haste]

Hi there,

I'm looking for a software or a macro to do the following. I've got around 1000 Word documents, numbered 1000, 1001, 1002, etc. Every document contains one exam question. Based on a design in Excel, I want to combine the documents, so I can get different versions (files) with exam questions.

So the output of a version would be like:
Version 1 contains question 1000, 1001, 1002, 1003, etc
Version 2 contains question 1004, 1005, 1007, 1008, etc
Version 3 contains question 1012, 1013, 1014, 1015, etc
Version 4 contains question 1000, 1001, 1004, 1005, etc

I would be nice if every question could get an automatic header based on their number in the version.

Version 1:
Question 1
<<1000>>

Question 2
<<1001>>

etc..

Does anybody know if this is possible? You'll find the example of the Excel sheet attached.

Thanks in advance.
