Can i change the values of certain variables in the PostProcessVolume Midgame?

[RoanExtraCool]

Basically what the title says, i want to change some values of the postprocessvolume. I want it to do that automatically in the game, so when it starts it has like bloom on 5, but after a certain point it switches to 3. (This was just for example)

The easiest way, is just put two volumes in the level, and instead of setting them to infinite, just make them large enough to cover the area you want.

Second method, is with one PP set to infinite, and use a blueprint to change the bloom
