Filter gd_listings shortcode by pricing package

Hi,

Forum seem to have deleted my previous post when I attempted to edit. Anyway, we’re planning to implement 3 price packages initially for listings (say, premium, basic, and free). Our client wants to display the listings in the country and city pages using a 3×4 grid in the following order:

1st row: Premium listings
2nd row: Basic listings
Preferably insert a banner add between 2nd and 3rd rows
3rd and 4th rows: Free listings

I’ve search the forum and played around with the core shortcodes and so far the best approach I could find is to use tags for each pricing package and display the listings using 3 instances of the gd_listings sc. Limiting the layout and post_number of the first 2 rows to 3 and filtering by their respective tags, inserting an ad banner below the 2nd row, then displaying the rest using a third instance of the shortcode. Works but less than ideal since we have to ask the client to duplicate the pricing package using tags for each listing. Is there a way to filter output of the gd_listings shortcode by price package instead?

Using latest WP, GD core and payment manager add-on. Thanks in advance.
