Is there any way players can have their own player account for DayZ?

What i mean for example:
PlayerAccount1 has played DayZ for an hour and his progress is saved when he logged out the game. he also logged out of xbox one.

PlayerAccount2 logs into xbox one and starts DayZ.
The player from PlayerAccount1 is loaded up instead of a new DayZ player account for Playeraccount2.

This seems to mean that the DayZ player accounts are tied to where ever DayZ is installed on the Xbox console.

So how can another person on the same console play their own DayZ player?
