GameplayAbilities and you

Hello,

I have another question: how would you go to undo a modifier when a game play effect ends?

I have 2 attributes : WalkSpeed and WalkSpeedMultiplier. I also have a Sprint ability. When this ability is active, I would like to set multiply the WalkspeedModifier by 2.0f for example. And when the sprint ability is ended, I would like to divide this WalkSpeedMultiplier by 2.0f.

Thinking about this, my assumption is that it is only possible using 2 gameplay effects.

Am I correct?
