I know you can set tier prices per group in the admin, but I require six groups with the same tier prices and one with non. So this would require creating seven sets of tier prices for each product.
So what i hope to do is hack the function that checks to see if a product has any tier prices associated with it - so it returns a negative for one group....
Having started to look around the core code - I feeling a bit lost, and wonder if anyone might be ale o point me to where I should be looking
