Skip default account page

When a user clicks on 'My Profile' and goes to 'Edit', it takes them to the default account page where they can set their passwords and timezones etc..
I have another profile type for stuff like About Me and contact numbers etc.. but to get to that page, the user has to click on a small tab to get to it.

Basically, I want to skip the page with the passwords and go straight to the main profile (it's a company intranet, so the first page won't really be needed).

Clicking 'Edit' on 'My Profile' takes you to "/user/uid/edit/" but I want it to take users straight to "/user/uid/edit/main"

Where would I add the extra "/main"? I've had a little dig around the user and profile 2 module files but can't seem to make anything work. Any help would be great!
