I have two documents - an internal meeting notes document and an external document to be sent to the client containing much of the same headings as the meeting notes.

Is it possible to somehow automate text written under certain headings in the meeting notes document to be transferred under the same headings of the external letter which is to be sent to the client?

I know I can just copy and paste it but due to the amount of letters we have to write, it's becoming quite tedious and time consuming.

Any ideas are very much appreciated! Thank you

If you are sending pdf rather than Word documents, in your Word document use a different body level paragraph style for the parts you want the client to see than for your own notes. Change the style used for your own notes to hidden before you produce the pdf.

I would but the letter being sent to the client has other information on it which is needed. Its templated differently to the meeting notes, I just want specific sections from the MN doc to be automatically pulled through to the external client letter.
