We are currently looking to move to Zoho CRM from another package.  I have a need to be able to track multiple lines of the same product for an account.  For instance, we track the product (concurrent user license) for every time a customer orders an additional license.   I need to track the date they bought the license, the amount, the maintenance amount, etc.

I tried to setup a multiple lookup record, linking the account module to the products module.  However it only let's me select 1 of each product.  

Is there a way to setup a "custom" table whereby I can track a 1 to Many association between my account and many lines of product purchases?
