Can I use the same 'products' database table to add a second product for a different eCart object.

I currently have a membership application form on our website that uses eCart for the user to be directed to a PayPal system to pay the fee after completing the form. The 'Add to eCart' behaviour uses the 'products' database table to get the membership data to build the correct transaction.

I am wanting to introduce a second type of membership that will be using a new application form with its own eCart object and my question is can I add this as a second product to the 'products' database table that the previous application uses. My concern is that I assume they will both have to reference there primary key, but when I inspect the code in the 'eCart Add to Cart' behaviour it appears to bind the data by the column name and not the data row.

such as - $ATC_itemID = "".$row_rsProduct['ProductID'] ."";

Hope this makes sense.

Thanks in advance
