I stumbled across exporting as an .SVG which had the Rasterise (Nothing) feature, and also, what I was trying to find, a Longer Text Span feature. So the text box expanded when you typed after exporting the project, rather than creating a new line when it reached the width limit
I realise it was probably, quite a random out of the blue question. But hope it helps others like me who are new to needing the more advanced features
