Is there a way to add text above and below the same arrow in sequence diagram?

Question

Something like (ignore the syntax, it would probably conflict with something, just trying to give an example):

A -> B : {above}Hello, {below}World

Which would result in an arrow from participant A to B, and there would be "Hello" above the arrow, and "World" below the same arrow.

Is that possible?

Thanks!

I also look for such improvement. In my case message over arrow is message name, and below arrow I'd like to insert specific parameters for that message. Something like "UEAuthentication_Request" above arrow, and below "SUCI, SN-Name"
