Increase the number of ads displayed by [adverts_list]

It’s possible to display more ads with [adverts_list] shortcode?

I mean, in the plugin option i have 12 ads per page, so everytime i use the [adverts_list] shortcode it shows 12 ads per page

it’s possible to increase this number with an attrubute? something like

[adverts_list display_ads=”20″]

This should replace the default setting
