I use the selective cycling method to choose which villagers I want out
it's a little tedious but it goes like this...
Wait for someone to ping to move
Say no (or yes)
If you say no, travel six days forward and six back
Load your game, someone will ping. Rinse and repeat.
This method ONLY works if someone pings, so if nobody does, don't travel six days ahead again as someone may move out.
