By custom new tab what are you looking for? You can make the new tab display your home page, I think a blank page, and with extensions you can make it do almost anything with a new tab.
I've configured it so that when i open a new tab it will by default open the url to my calendar. It does not select the url in the navigation bar, so if i want to input my own url i first need to select the calendar-url so that my inputs deletes the existing text. I do think that the custom url new-tab is an extension though so that doesn't really help my case (not at the computer so can't check).
