Self fill in shipping option

[magicseederireland]

Is it at all possible to have a blank section in the shipping dropdown that a seller can fill in them selves the name of the shipping company/option,

Reason i ask is that i am looking into dropshipping products and the suppliers are in the UK and i am in Southern Ireland, yet to find a dropshipper in this country,

If this is possible i could then have

Domestic Shipping as parcelforce (self fillled in) Postage to Ireland
International Shipping as Royal Mail (self fillled in) Postage in UK

Hope that all makes sense and thanks
Phil
