Configuring Store For 3 Revenue Channles

I am not sure that this is the correct channel, but here goes

We have a cs-cart store that does online sales, sales from a retail store, and vendor sales. All of the sales are clumped together as one. We have just implemented Google Analytics Enhanced Ecommerce to record the sales which obviously include all 3 sales channels.

I was wondering if there was a way in cs-cart to differentiate between the 3 different types of sales?
