ShippingQuoteIf objects have a title and a description. But in the Shipping module UI I don't see any field to set them.
When calling ShippingMgrIf.getShippingQuotes() all the shipping quotes have the same title & description and I don't know where these values come from.
Where can they be configured?
OTB each shipping module has a properties file for each language it supports. The title and description are in the properties file. If you wanted to make them configurable through the admin app you could add an extra couple of configuration variables to the module which would show up in the Admin UI when you install it. Obviously you'd have to modify the module in order to pick up the values from the new configuration variables.
