The bottom of a SawStop insert is difficult to replicate in a shop made wooden insert.
If we limit the application to vertical cuts, and exclude maximum height of the blade, then the insert becomes much simpler, and still works most of the time.

Wooden inserts have the advantage of zero clearance around the blade. Also they are quick to make and low cost so you can have one for each dado width.
