Yes, and it is pretty easy to do that! When you create an offering on Ticombo, you can choose the split type in the second step. You can choose between the following options:
No split: All tickets can only be bought together in one batch.
Any split: Any number of tickets can be bought, e.g. if you sell 4 tickets, each number can be purchased: 1, 2, 3 or 4.
Don't leave 1 alone: In this split type, we make sure that all numbers of tickets can be sold, but no combination, where only one tickets would remain. This is often used to make sure that there are always two tickets left, because two tickets are easier to sell than one.
Remember that all tickets in one offering always need to be adjacent.
