Another Shipping method

Hi.

I have one product with one special shipping method.

Not UPS. So how can i add this shipping method in the checkout.

My setting is, that from 1 product i have a flatrate with UPS. So, when the one special product is in the basket, UPS Plugin thinks taht is the flatrate price.

The problem is: I can not connect the
Shipping method : UPS with shipping class UPS.
The Plugin has no option for that.
