where is the support of this plugin??

Ok I hope you will understand this. I just purchased the SOBI plugin and installed it. here are my structure.

Main category - ( show all listing -ex company A is listed)
-1st category
-1st sub category - ( show listing - company A is listed )

when I click the listing in the main category which is "Company A" the url is mydomain.com/companyA

but when I go to 1st sub category and click the "Company A" the url is mydomain/1st sub category/companyA

but they have the same content.. what I want to do is I want to have the same url of my main listing and the sub category listing which has the same content so it will not be duplicated.

is that possible ?
