Modify the Data Load wizard to remove the check for unique columns

Question

Hi,
I'm trying to make a Data Loading Wizard into my application, which basically works nice except for one thing:
I want to remove the check for unique columns, and insert ALL data which the users wants to upload.
(Like the Data load utility under development).
The reason is, that the data I want to upload is an export from my bank statements (in XLS / CSV format)
And these exports don't have any primary key.
Using the Apex wizard created Data Upload pages, I will loose data in case I had two identical payments in a day.
Is there a way to do this, while keeping the pages created by the wizard to make Data Loading pages?
apex 4.2.1

I would suggest to load the data into a view and process the records into the real table(s) with instead-of-triggers. When you add a "1=2" where clause to the view, there never is any data and everything will be loaded.
Otherwise you have to have a "real" PK value, like a timestamp or a statement_nr+line_nr.
