Same thing applies to using a custom form on importing as it does for custom
fields - the standard import function doesn't support that. You'll need to
either 1) write your own import function or 2) get a 3rd party program (such
as ContactGenie - link below).

For various options - also suggest you take a look here:

appropriate page on Slipstick so take a look around the entire site).

Outlook doesn't support importing to a custom form. You'd have to write
custom code or use a third-party application. See
