Jumping high when stomping a enemy

Hello, I'm making a game like the Mario series, and we all know when you stomp in a goomba/koopa/etc... you can jump much higher when the jump key is down, I trying to do that in my game but i don't know how to do it, I tried Vector Y, but you can jump higher if jump key is down, and I tried to enable double jump when you stomp the enemy, but you can do that with only 2 enemies, because is double jump (duh), Is there any solution to this?

Does increasing the jump strength on platform behaviour not work?

I tried Vector Y, but you can jump higher if jump key is down

Couldn't this be avoided by a simple boolean variable setting?

I mean, when the jump key is down, jump strengh increase, but if the key is not down, just the same jump strenght
