Possible to specify the link-local address/avoid EUI-64 addresses?

[eddy]

A couple IPv6-related questions:

1) Is there any way to specify the link-local addresses and avoid the EUI-64 auto-generated addresses?

i.e. I'd prefer to see fe80::1%igb0 as my link-local instead of fe80::4242:42ff:fe42:4243%igb0

2) Similarly, when an interface's IPv6 Configuration Type is set to Track Interface, is there a way to have the tracked-interface always use the ::1 address (for example) of the delegated prefix instead of the prefix plus the lengthy EUI-64 address?

I find using "sane" addresses for the gateways makes dealing with IPv6 a little easier...

Thanks for any suggestions.
