I have not tried this with previous versions of PRPC.
The text is sent to a third party service, therefore we cannot modify the service. There are restrictions in terms of the length of each line of text sent to the service. For example, it could be: maximum 100 lines of text, maximum 50 characters per line.
We need a UI control to help the user enter the text in the required format.
I will give the edit input a go. Any other suggestions are welcome!
