Limit amount of nodes to CCK date field

Ok here's my situation. I have a restaurant user and a "menu" content type and I want them to create a daily menu for each day. I thought this module would be my savior but now I notice that it allows them to create one node per day, not for each day.

Let me clarify. I want the user to be able to create one menu for Feb 26, one for Feb 27, one for Feb 28, etc. He can go in and create 10 or 20 menus today Feb 25th but they all have to be for different days. The menu has a date field where they select the date for which the menu is.

So now that I installed the module and made the rule I notice that this will actually let user create one menu a day. So maybe today they can create the menu for tomorrow and repeat every day but that's not the idea. Users should be able to go and create all the menus for the week or month if they want to (but each one for a different date).

Can this module help me with this? Does anybody know how I can achieve this? Should I ask in the Rules issues? I do know PHP but I'm new to rules so I see in rules I can check if the date value is equal to something but I don't know how to do "check if there already exists a node with this date". Also I have another role that will be able to create 5 menus per day so I don't know how to do "check how many nodes the user has with this date and if it's 5 then don't let him create a new one."

Thank you in advance for any help.
