At present I have several products and several customers, each associated with a form and each with lots of fields.  Each customer buys a portfolio of products on a regular basis, so I use the multi-relationship to assign the products to the customers under the customer form. 

First Question: In the customer view, it lists the products with comma in between.  Is there a way to have a line break in between instead?  This will make the list easier to read.

For each product, I would like to generate a list of which customers buy that product.  I tried using views and reports to see this information, but to no avail.

Second Question: How can I generate this list?

Thanks for anyone's ideas!
