Having multiple start pages would be difficult and confusing. Let's say, you only want to have StartPage#2 show if you have the BlueSword ... putting in such a feature would be too limited.
Instead, you can do this. Make a chapter start page "hub" that will have all the links to go to the start page you want. You can achieve the same effect -- show a new link everytime youvisit the page (via a VARIABLE):
Link#1 - show only when CHAPSTART = 0, increase CHAPSTART by 1 when clicked
Link#2 - show only when CHAPSTART = 1, increase CHAPSTART by 1 when clicked
Link#3 - show only when CHAPSTART = 2, increase CHAPSTART by 1 when clicked
etc ...
As an author, you'll have to figure out how to make the "hub" page fit in with the story. But normally it's pretty easy to do ... could be as simple as "you walk back to the city ..." Who knows, whatever works for your storyline.
