I do not know if it is possible, that's why I ask.

I already searched solutions on Google, but found nothing. I think that I don't know what keywords search for. For example, looking for variations of "different versions" return useless pages.

So, it would be useful if somebody just gives me more effective search terms.

I guess that what I'm looking for is already implemented in Word, or can be done using some feature, like corrections for workgroups (about which I don't even know where to start), or working with listings (I know that is possible, for example, to write a mail letter and print one for each person on a list, and I don't know how to do that ¿maybe fields?).


My boss asked me to keep different versions of the same document (80% of it should have common text shared between documents), and I can see that it would be a maintenance hell to edit each one and copy pasting the common sections.
So, I believe that is worth the effort, because I foresee that, maintenance complexity will explode exponentially.

I can use macros, and I have experience writing macros in VBA and also VB.NET.
