What 'Token Value' should be given for getting the url www.example.com/product1-vs-product2 for the comparison of products created via Node Compare module?

Node compare module: https://www.drupal.org/project/node_compare
Demo product comparison page: http://nb7demo.drupalka.ru/compare/type/product/54/51 (In this demo page, the '54' and '51' are the node numbers of the comparing products.

I have 'custom content paths', for example www.example.com/mobile/nokia-n70 & www.example.com/mobile/samsung-s2. So now I want www.example.com/nokia-n70-vs-samsung-s2 as the url of the comparison page and I want the page title as "Nokia N70 vs Samsung S2 | Compare". How can I achieve this?
