MarketPress:Asigning different page for store & products

Hi

I am using MarketPress with FrameMarket (child theme) and wish to show a different page when one clicks on “Store” (nav menu). Right now both the Store (main menu) and Products (sub-menu) showing me the same page “our products”…from where can I control that and also wish to change “Products” to read as “Browse Products” where can I add this word “Browse” before products in the sub menu.

Thanks in advance
