Hello!
I feel your description is incomplete. I have some questions about the job: which version of blender do you prefer, and what will be exactly in the pie menu. From version 2.80 the pie menu itself is just a little step, so in this case, i feel the huge part of the job is in the backend... Or you prefer an older blender version - before the pie menu addon exist - and you want it be there.
I'am new here, so I don't know what is the good solution,therefore I made the biggest bid, to write you : May I ask you to refresh the description ?
Thanks
