Ticket Tag to add an item to order

I want to use the ticket tags on the left of the screen to add an Item into the menu.

Basically I want to press the button and it prints a line on the ticket that says Serve First, Hold and Mains Away. I need to be able to hit Serve First, add a few items and then hit hold and add more items that need to be put on hold. Then later i can open the ticket again and hit Mains Away which will print to the kitchen to let them know I want the rest.

If possible I want it to only print items that are tagged with Serve First and not print the rest until Mains Away is pressed.
