Lisa, take a look at Claquos 2 | Pie Chart Builder for InDesign
https://www.indiscripts.com/category/projects/Claquos

Hi, i have been using vjoon k4 the last 7 years for our magazine. It is very flexible and it can be used to automate many of the task that you are mentioning.
If k4 is useful for your production i cant say, give it a try by contacting one of the resellers or ask me something more specific.

We are producing a magazine in 33 local editions with the staff spread in 9 different regional locations around the country, Sweden.
