Guitar String indicators in Dorico 2?

I’m trying to add string indications, but when I go to the properties menu I only see fingering options. When I search this, I find a lot of results with “new features for Dorico 3.” Are string indications actually exclusive to Dorico 3, or is there some way to get them in Dorico 2?

String indicators inside the staff were only introduced in Dorico 3, so no unfortunately you can’t show them in Dorico 2. However, string indicators outside the staff (ones often shown with a dashed line after them) are available in Dorico 2 as they’re playing techniques, although the dashed lines for when they apply to multiple notes were also only introduced in Dorico 3.
