Putting a description with Shipping options

I would like to offer multiple shipping options, which differ by number of days for delivery

e.g.

Name Description
Standard 2 - 5 Days Untracked
FedEx 1 - 2 Days Tracked

I know I can put a Name for the Shipping Option, but I really don’t want to also include the Description
as part of the Name as I download Orders through the API and it’s horrible to work with.

Is there any other way I can show a Description (e.g. 3 - Days) alongship the Shipping Option?

Thanks
