cut a 'lead-in' into piece of a part on a varying angle

In the last months, we started to optimize our parts to be cut faster by our plasma by doing the following:
Parts like this

Get a 'lead-in' like this

is there a better way to do this (fewer/smarter features) than

  1. cut extrude
  2. fillet (full round)
  3. fillet (full round)


It just breaks so often, when changing a part.

Did I miss something very obvious?
