How to lock a page to top sites

Even though I visit a couple of pages way more often than others...they never show up on my top sites homepage. Is there to force these to show up and stay there? I thought the purpose of this feature was to display the pages you most often frequent. There is nothing abnormal about the two pages...one is my bank and the other a major brokerage firm. I'm trying to stay loyal to Safari...but little things like this (that work fine in Chrome) are eating away at my loyalty.
