Perform the import, then use one of the scripts or tools on the page I suggested to update the MessageClass property of the imported items to point to your published custom form. You can check whether the items were updated properly by adding the Message Class field to any view, so that you can see what form they use.

The data I ma trying to import only contains standard fields data, however I
want them to be displayed using the custom form I have created so that I can
input the data into the custom fields.

I have tried importing the data and changing the form with no success.
