Putting clamps on a work pice

Hello, I was wanting to sugest maybe putting a little tool that would allow you to show where your clamps where going to be, like how big the clamps are and how tall. That way when it does the tool path it will go around them, maybe adding in like how bit of an area your head is to include the dust port and such. That way we can use clamps and be totally safe… I know that you have the safe height in the settings and such, but some times i have found i did not take into account somthing and it was most of the time the clamp and i ended up haveing a bad day.
