Feedback: Please add "lock for.." interaction for grills

I loved it when we got to solve the addiction of guests in a house always just playing on computers by locking the computer for eg.the household only.

Now my guests are using my grills all the time brewing  herbal remedies and running back and forth through my house from kitchen to yard and also my controlled sims overuse the grill though there would be excellent leftovers in the fridge.

Could you please add a quick fix and make grills lockable like the computers?

Other sims don't want my sim to cook in their houses, nor do my sims want their guests to do that while visiting.

I'm tired of building a fence with a locked gate around my grill to avoid this :<
