Yes
Give each entity an extra property: the original value of the planning 
variable property.
For example:

class ShiftAssignment {
    Shift shift;
    Employee originalEmployee; // Just a normal problem fact
    Employee employee; // Planning variable
}

then add a rule which adds a cost for every entity that moved

when
    ShiftAssignment( originalEmployee != employee, $employee : employee)
then
    // add soft constraint for -(employee.getMoveCost()).

You can make the move cost depend on all sort of factors.
