(I hope this is a more appropriate location than general InDesign discussion)
I've been looking for a script to automate a tedious, repetitive process. What I do is to use a data merge on a master to set up a series of very similar documents with a partner's information...we have LOTS of partners. There are a total of 10 different documents all in one long InDesign file.
After their data is in, I export the pages out in 2-page increments (except for one wich is a 4-pager) as seperate PDFs. It's the same set of documents every time with the same file names, it just has different contact info on it.
If it saves the right pages over an old copy OR if it exports new PDFs with the right names, that would rock!
