I suppose you could tin the wires beforehand. I think that is what Halo does with the wiring in their RC cans.
I disagree with the tinning of stranded wire and then inserting it into a screw tighted connection. When you tin the wires, and then compress them, the solid mass will sometimes fracture. This leads to a loose connection. That is why soft copper ferrules are used with fine stranded wire when using screw down connectors.
