Question on editing registry

[xefe]

Have two things I am trying to do that may possibly be achieved through registry edits.

Was hoping someone could either provide me with the answer or point me in the correct direction.

With the new 6.5 rom, in my calendar program; only the default appointment 'category's are available(business, holiday, personal, seasonal). Outlook, in 6.1 I was able to choose from my MS outlook categories for it. Is there a place I can edit the registry to at least add a few choice categories in the 6.5 version?


2.) The contacts for 6.5 offers ability to sort contacts by 'Groups'. Is there a way to edit registry or settings or whatever, where only CERTAIN groups are shown instead of ALL groups?

Even if this is not an easy task, If someone could point me in the direction to learn how to accomplish this it would be greatly helpful.
