Probably. But I would make it as simple as possible on the server. Before you even order, identify the 3 groups that will be on separate checks--two groups of 4, each with one member, plus the separate group of 3.
When it comes time to pay, show your digital ID cards and make sure the member on the card is the one who pays. Then settle-up the finances among your group later.
Don't expect that you'll be able to mix and match after the fact, having the server try to sort out which people should be on which checks, where the discounts are coming from and who is paying. If you and husband are the members, you should each have 3 others on your check, be able to show ID cards and pay for that check.
Maybe you'll get lucky and the server will just apply discount to all 3 bills. But don't go in expecting that.
