The idea is to add optional feature "Remove this" or "Trim Solit" in Split Body tool.
It's often used this way but it requires two operations now: (1) split body (2) remove unnecessary parts.
How it's currently implemented in Inventor - all-in-one tool window with several tools: split face, split body and trim solid.
