How do I create multiple locations for the same call for VHF contests?

I have created an account for K7MKL/VE4 in EO00 but also need independent accounts for at least 4 other grid squares. The date ranges for all calls will be identical for the June VHF Contest I operated in 2011 and, as a result, I cannot create any additional locations for K7MKL/VE4.

I attempted to get creative with calls, appending them with the grid square, but that was, in retrospect, a bad idea :>) Now I must determine if those calls can be deleted and find a way to create the accounts for each grid square activated.

Any suggestions will be appreciated.
