Personalization Purge - Leaves home page layout?

Most users use the gray E10 home pages / tiles layout. I’m testing personalization purge on Pilot and noticed that it did not reset users home page layouts. Is there a way to reset these home page layouts without going to each client and clicking settings -> homage page -> reset layout?

Also, once reset, is there a way to globally set a default layout besides editing each user via user account maintenance?

(ignore that second question… I see this option in company maintenance).

Still, how to I in bulk wipe all user home page layouts?
