Discount for 2nd Session

For our club matches we run both morning & afternoon sessions.
The shooter selects this currently by picking either a 100 squad (morning) or 200 squad (afternoon).
Is there a way to set up a discount if the shooter signs up for both sessions?

Martin,
You can easily set up a discounted second gun or session.
But, this is not fully automatic to whether it is a 1st gun(session) or 2nd gun (session) and still requires the shooter register two times. We also suggest that the match Admin uses their own oversight to watch for folks registering incorrectly. Someone could choose the discount and only register one gun/session, the MD would have to fix that.
Here is how it looks. (You would just have to change “gun” to “session” in this example)
