Create Multiple documents with small changes quickly

Hello,

Dont know if this is possible, or if i can explain it well but I will do my best, as the current method we have is inificent and tedious if there is a way to have it improved to make things quicker it would be nice.

So here goes, ill try to be as simple as possible. Basically, I have a 3 page document that i need to make 50 unique copies of. Each copy of this document is identicle except for one simple aspect, each page of the document has a cerial number. So copy number will a cerial number of XXX1 on each page. The next document will have the same information but the cerial number will be XXX2. etc etc, until I have 50 document with cerial numbers from 1-50 recpectivly. The current process involves edditing each individual documents codes one by one until the process is completed.

My question is, if the above has been understood. Is there a way where I set it up where I will be able to save the document once, and it will generate 50 copies with the cerial numbers automatically changed, or is it simply not a feature that is supported??

Thanks for any help given,

George
