How to add a 4th Stair Stringer to Deck Stairs

[jcb777]

The stair edit dialog box only has a selection to add a 3rd stringer, how can I add a 4th stringer?

I’m not sure if I understand you correctly. Both stairs (sketch and component) have options to apply infinite (or almost) number of middle stringers.
