Yes, you can and our system actually fits very nicely with what you are wanting. In the software, you will create a product profile for each product that you sell. You can then create a campaign for each product. Each campaign can then be used to fill up the library of scripts, emails, and templates.
You will have a drop down button that will list all of your products (technically all of your campaigns) and when you switch from one to another, all of your documents in the library will switch over to the other product that you selected from the drop down.
