Shipping rules for Calculated Shipping Methods

There are no rules available for calculated shipping methods.

We would like to restrict calculated shipping methods the same way as custom shipping methods

For example right now we use calculated FedEx Freight rates, but we want this to be enabled ONLY when the order is over 80 lbs, otherwise the method appears for all orders and clients question what is the difference between paying $10 FedEx ground and $150 FedEx freight for a 1 lb item.

The rules available for custom shipping methods should be available for calculated ones to limit the method by subtotal, region, warehouse, weight, etc.
