Podlove Subscribe Button - Limit App Options List?

Is there a way to limit which app options appear in the app list when a user clicks the Podlove Subscribe Button? Too many options can be confusing to a user who doesn’t understand this stuff, and the goal is to make it as easy as possible for a non-technical user to subscribe.

Also, it would be great if we could set a default choice at the top of the list such as the Podcast app for iPhones/iPods/iPads or the Google Podcast app for Androids. Is there a way to do that as well?
