Boolean custom fields?

[EvanGR]

Hello,

I need to assign the following properties to a collection of products: LEFT, RIGHT, FRONT, BACK.
A product can have none, one, or a combination of those.
e.g.
Product 1: -none-
Product 2: LEFT
Product 3: FRONT LEFT

etc...

My first thought is to create 4 boolean custom fields, and assign them to the products.
But I have not used boolean custom fields before, and I am not sure this is the optimal way to do it.

btw... the custom fields will be assigned in bulk mode, through the use of a CSV Improved script.

Any thoughts?

Thanks
