Hi, I've been trying so many ways to fix this, I have lots of documents that I use as a set of documents like a package of rules for a company. There are about 200 documents in the set. I need to change the colour theme for shapes and text inside the documents as fast as possible.

I create a custom theme and start using it on each document as I go through them and some documents it works on and some it only changes the shape colours and not the text and others it changes both but to the wrong colour set.

The text that I'm changing colour on is titles which are styled as "Heading 1".

I want to be able to open a document and apply my custom theme and it works on all the documents that I apply it too.

Ultimately I would like to find a software that allows me to input theme colours for shapes and fonts and press enter and it updates all the documents in a chosen folder.

I'll settle for one document at a time regardless.

Any ideas would be much appreciated.
