Import and Export Wizard SQL Server 2012 - sql

Question

Is there an feature on the Import/Export Wizard of SQL Server which allows me to do the following? If so, how can I go about it...

So I have the table above:
I want to add the cost column in from a Flat File (CSV source, made on Excel).
Can I do this on the wizard without removing the other data - I have tried multiple different options on the wizard, but I seem to keep removing the data or the data added creates another set of row, so it will look like bottom table.
I do have a primary key on this table and I have set that to increase automatically by 1 - I have also got foreign keys, though I had to remove the relationships temporarily to allow me to even get the data onto the table.
Sorry the formatting isn't clear - The top table represents my table and the bottom table shows what happens when I input data - What I want is a the cost column aligned with the old data.
Any help would be much appreciated.

If you want to update existing records in the table you need to be able to identify a relationship between the rows in your table and the rows in your CSV file.
To update the rows in the existing table import the CSV file into a separate table. Then run an UPDATE statement like the one below to update the rows in the existing table with the data from the new table.
UPDATE T
SET T.Cost = S.Cost
FROM dbo.MyTable AS T
JOIN dbo.CsvInput AS S
ON T.ID = S.ID
