Subscriber page active settings changes

I have two subscriber pages: one for non-ajax and one for ajax. I do not want to show the ajax subscriber page in the list of available subscriptions, if a user enters my phpList site without the parameters p=subscribe and the id.
I have set my ajax subscriber page to inactive.
The problem is that whenever I make any changes to the ajax subscriber page, the page will be active again and will be shown in the general list. So after every change I have to remember to deactivate the ajax page.
