MarketPress Virtual Shop Pages and Permalinks

I'm trying to use get_permalink() and page specific dynamic sidebars with the MarketPress plugin pages.

From what I can see, the default MarketPress structure of /store/shopping-cart, /store/products/ etc. are virtual URLs and don't trigger the above mentioned functions.

How does one interact with these virtual pages using standard WP functions, or is there an internal $mp variable that can be leveraged?

Please let me know; Thank you!
