Best way to play music continuously between level WITH Quartz? and keep clock live!

I saw the “ignore flush” in here:

“Clock will persist across level changes” Oh oui!.. but…

But how do I use it? (with Blueprints)
It’s a C++ only “please recompile your engine type?”

I do use “ignore level change” when I create my clock settings(“MakeQuartzClockSettings”), but that doesn’t help.
