bbPress.org

Hello,
Is there a straightforward URL to be able to jump directly to a bbPress forum topic’s last page ?
I have tried different URLs like :
   (site_name)/forums/topic/(topic_name)/page/last/
   (site_name)/forums/topic/(topic_name)/page/end/
   (site_name)/forums/topic/(topic_name)/last/
   (site_name)/forums/topic/(topic_name)/end/
but none of these work, whereas a URL like :
   (site_name)/forums/topic/(topic_name)/page/13/
works quite right !
Thanks.
