custom permalink

Hi mark
today i have purchased Directorypress theme. i want to migrate from my old directory script to directorypress.
previously i was using https://www.salephpscripts.com/ .

my first problem
in old script category link look like this – https://www.clickerindia.in/categories/automobiles
sub-category link look like this – https://www.clickerindia.in/categories/automobiles/bike_dealers/

but in directorypress both category and sub category look like this

https://www.clickerindia.in/categories/automobiles/
https://www.clickerindia.in/categories/bike_dealers/

and i want links look like old script in directorypress theme

my second problem is with slug of listing titles

i want slug like this “listing/barbie_dolls/” in place of “/listings/barbie-dolls/”

thanks
vinod
