Boolean Union Problem

[Anonymous]

Hi Autodesk Community,

I am having another problem with my Booleans. The issue I am having is because I created a face through a boolean difference and now I want to boolean union objects to that flat face while keeping the flat parts level. Is there a way I can add more edge loops to the face so that it will boolean union cleaner? Or is there an easier way to do this? Thanks as always!

Best,

Shane
