Add a multi-laisle style

Hello, here I am again for another question, I wanted to add a style of multiple link with Phase1 / Phase 2 / Phase 3, when I want to number them I realize that I have to write in the formula "Lx-" so as not to have numbers with the same child marker.

See the attachment on the right what I would like to have and if you could tell me if it is possible.

Thanks in advance

You have to go to the "link style manager", place yourself on a group, right click: "Properties" and in the "calculation of the order number for multi-threaded links" section, check: "Different for each thread."
