Steve, your idea is close but NOT really something you can use on your sled.
Your sled!
The two best options are either a dedicated sled for each angle OR a sled with a replaceable insert
wherein you can swap out the angle by swapping out the insert.

Check with LJ Darryl Masterson, he’s got it perfected. ;-)

Cheers,
Gary
