For AW girls, as long as the link has been provided that contains the individual WG's number, then there should be a link at the bottom of their review to all other reviews on UKP, so you can see that "Claire of Wakefield" for example has 5 other reviews on here, and can then view them all by clicking on the link.
I would presume this is a lot more difficult to do with parlour and/or agency girls though? I'm not a techie in the slightest so wouldn't know for sure!
