How to clear statistics for a player individually?

Follow my reasoning:
I have a player in an establishment that had x displays in 4 months.
So for some reason I change this player of establishment and it will have after some period and exhibitions.
When I fetch the statistics from the player they will be compromised as it will also count the previous views from when I was at the other property.

I know that excluding the player and add again it zeroes everything.
But suppose I can not or do not want to create another player.

01 - Is it possible to reset the statistics of a particular player, or all players at once?

02 - Is it possible to do this by deleting the data in the DB?

03 - If this option does not exist yet, how about adding these options in the next upgrades?
