Is there a way to make the player pawn collide with the root component of an object if they are gripping a grippableStaticMesh component of the same object?

For example - the desk in the example project by default has custom collision which has pawn set to Ignore. If I set the pawn checkbox to block, the player can no longer walk through the desk - but they still can if they are holding onto a drawer. Is there some other setting i’m missing?
