If you want to, you can simply top up the wax after washing and drying the car as per usual. Don't clay or polish unless you want to get back to a clean base from which to start over.
It's generally taken that you shouldn't carry out correctional polishing more than 2-3x per year as each time you do this, you take a little clearcoat off. Polish too often too aggressively and you'll have clearcoat failure resulting in the need for a complete respray.
There's nothing stopping you from wash + dry + wax or wash + dry + clay + wax, bearing in mind the clay will remove all previous products used.
