Is there a way to create a tracking code that does NOT apply a discount?

[Flow13]

Hello!

I'm assisting a local school with a fundraiser and want to implement a tracking code for all orders from said school.  The only issue is, I'm not applying discounts to the orders using the code, but rather tracking all purchases made with the code so that I can then donate a portion of each sale to the school.  Can I do this in Shopy itself (I only see discount options) or is there an app that can accomplish this?  Thanks in advance!
