Modify Shortcode to specifcy which menu to show

Great plugin! I really need it to let me designate either:
1. Which MENU to use, from which to draw the listings. Or,
2. Which PAGE TEMPLATE TYPE.

Any chance you could program it to do this? (I’ve searched the documentation, and I’m 99% certain it doesn’t do either.)

I want an alphabetical listing of the company’s service providers, each of which have their own page on the website. But I don’t need the listing to include the rest of the site’s pages.

Or, for what it’s worth, each service provider page uses a custom page template. So if I could have the plugin pull in only the pages using that template, that would work, too. (All things being equal, I’d rather have it pull by menu, however.)

Any chance you could write this into the plugin really soon?
