Hello, we purchased the rev a shelf already installed in a cabinet under our island. It has the lift shelf and then the sliding lower shelf underneath. Our problem is that we own a KitchenAid Pro - the bowl lifts up and down and the overall height of the unit is stationary. We do not have enough clearance for the unit. Is there a modification that you suggest for the KitchenAid Pro user? We could potentially remove the lower drawer and lower the shelf entirely but then I am not able to use it at counter height...thank you!
