Can I cancel my previous submission and file a new one?

Hi,

I made a site suggestion on 21 December 2014.

I now realize that the category I have chosen might not be the best one and I noticed a better category today.

I originally submitted in;
Regional: Asia: Indonesia: Provinces: Bali: Travel and Tourism: Travel Services.

I wish to change the business listing and add it to;
Regional: Asia: Indonesia: Provinces: Bali: Business and Economy: Shipping, Storage, and Logistics.

What is the proper way to go forward? Shall I ;

a) request my 21 December 2014 submission to be cancelled and resubmit?

b) just resubmit a second time?

c) ... ?

Thank you

P.s. Happy to supply the domain name if needed

An editor will move the site if there is a better category for it, but if you wish to suggest the site to another category now, just do so.
