Can't get text concatenation working

We are trying to get ChatGPT to create meeting minutes however the problem is is that our transcripts are typically over 30,000 characters. ChatGPT has a upper limit of 10,000 characters. So, we’ve split up the transcripts into 10,000 character chunks however cannot work out how to get ChatGPT to aggregate the text and then produce meeting minutes for the entire set.

Is this even possible?
