Multiple Products within an order

hey guys,

I am a newbie in CRM, I am not a developer, i just customize the system views and options.

My company sells AT&T products through several campaigns.

for example: 

Campaign: Winback

Price list: (Within this campaign):Long distance Call, Short Distance Calls

now every Product Family has Sub Products:

Product list: Long distance Call

Sub: X, Y

Product Family: short Distance Calls

Sub: C,V

and then each has a quantity of course.

the problem is that a customer can buy two different Sub Products within the same campaign. (each belong to a different Product Lists)

Is there a way that i can facilitate that?

the problem is that you can only add one price list per order. i need two and sometimes three.

is that possible?

I appreciate everyone who took the time to read this post :)

Thank you
