How do I modify jump strength with blueprints?

I want to make it so a user can configure how strong their character jumps. The part I am stuck on is: how would I access and modify the character’s jump strength in a blueprint? It would be nice if I could apply a multiplier to the jump strength (e.g. 1x for normal, 1.5x for a stronger jump, .5x for a weaker jump, etc…).

set it up like so

The Jump ZVelocity is necessary for changing the character jumping speed, but I think it would be better if you also change the Gravity Scale value, so you could control both, the jumping speed and the falling speed.
