Changing 'view profile' options

Management has requested that the “home:” field be replaced with “fax:” in the “View Profile” screen. (this is the abbreviated version you get when you say ‘view profile’, not the full profile) We don’t have a need for easily seeing home phone, but do for fax.

I have not found documentation on changing what you can see here. Does any exist?

Can someone point me in the right direction?

I suspect you will need a developer to make the changes and rebuild Spark.
