Need Help in Microsoft project 2007(2010)

Hi,
I am working with Microsoft project 2007(2010). There is a standard including form in it for an automatization project and now I want to change it. So i need two more options in TAB. One is "Predecessors" link with access database (added by const.) and another one is standard fields, access query which I added by himself.
Can it possible? Please share your opinion and suggestion.
Thanks.
