You do realize that if you want to collect from the market on a 7 hour schedule, synced with PoP, you can simply do so? Nothing is forcing you to collect after 6 hours.
Now if you had asked to change PoP to 6 hours, I could understand that, but that's not what you asked for. Why on earth would you ask to make the game worse, only because you, personally, prefer not to use it? SMH
