Label strings in alternate tuning

I am fairly new at Dorico and I’m trying to create tablature for a six string guitar with an open G tuning. I have finished the note input and it looks ok. But I need to label the strings on the tab, to show how the guitar should be tuned. I would like for the note names to be to the left of the first measure, or if that isn’t possible, just a small chart at the top of the piece. Is this possible? I can’t seem to find much about tab in Steinberg’s tutorials. Any help would be appreciated.

Thanks
Ron

P.S. I have Dorico Pro if that makes any difference.

Dorico doesn’t currently have any dedicated features for showing the string tunings at the start of the flow, so probably the easiest way to achieve that for the time being is to use a text item created via Shift+X.
