How do i edit "Thread Title (1 2 3 ... Last Page )"

[zigx]

I would like to modify the "1, 2, 3" individually...

for example...

This is what it has by default:
<a href="$address&amp;page=$curpage$address2">$curpag e</a>

i would liek to make it output

site.com/thread$threadid-page$pagenumber.html

is there a way i can edit how $address is built or something? and do you know what curpage and address2 are for?

Thank you!
