hierarchical instanced static mesh destroying instances, having gravity applied

I’m very new to this so for forgive the uninformed language used. I have a hism (tile group) set up as the platform for the player to drive on and I have the player controller set up so when the player drives over an instance of the tile group, that instance is destroyed. What I would like to know is how I can effectively have the part the player ‘cuts out’ of the whole fall. Any help is appreciated!

A video of the what I’m talking about.

Instance replacement.

Replace the object from an hierarchical instance to an actual mesh, on which you set simulate physics and collision.
