How to Price adjust for selected products?

Is there a way to set and apply a different pricing formula for a different group of products, for example:

Products in Catagory a have a price minimum of say $3.00 and sales price a 3x multiple but I want products in Catagory B to have a price minimum of say $10 with a x2 sales price multiple, is this possible to do without having to go through each product individually?

Thanks
