Horizontal Lines

Hi there! I’m trying to input a wavy body line that goes wide to narrow, versus narrow to wide. Dorico only has options for narrow-wide, variable, or regular. There’s an option in the Properties panel to “Reverse”, but when selected, there is no change to the line. I’m curious if there’s something I’m missing here, since I would rather not have to create a new playing technique to get this line I’m looking for. In the included screenshots, I’m attempting to reverse the narrow-wide line (at least, that’s what the option implies), but it just isn’t doing anything.

Thank you for your assistance!
