Solidworks Assembly- Lock the Tree from Expanding?

[buggsbunny]

Working in an assembly, if I click on a component subassembly in the view, it expands the tree. This creates a mess, and I have to go through the tree and compress everything.
Is there a way to lock the tree at the subassembly level?

Maybe not lockable, but shift C will collapse it.
