Can any one suggest how to modify the current url structure on interspire
Change the url structure on my interspire e-comm portal

The current structure is
www.egully.com/
# /products/Product Name
# /category/Category Name
# /pages/Page Name
# /brands/Brand Name

I want it to be configured so that the structure appears as
www.egully.com/
# /Product Name
# /Category Name
# /Page Name
# /Brand Name
