adding allow buyer cart cost customer customers day delivery development discussed domestically enhancements features mail next offer option options postal priority products registered select selection separate service-level services shipping standard support working

Does anyone know if there is a way to allow the customer to select from different priority postal services. I would like to offer my customers the option to:
a) Use standard mail
b) Use priority next day delivery
c) Use registered delivery

Each option has a different cost.

I could do this by adding the mail options as separate products, but is there a way to provide the option in the cart?

p.s. I am based in the UK shipping domestically in the UK.

At the moment, we have no way to allow a selection of shipping services for the buyer to choose.

Development has been working on some enhancements to our shipping features, and we have discussed adding support for a shipping service-level selection in the future, but that's about all I can say about that for now.
