get spotify bucket track list in ENiOS

Hey all,

I'm currently working with the Echonest API in iOS (ENiOS) and right now I'm trying to use the available request feature at playlist/static in order to generate a playlist of Spotify URI items. Unfortunately, the style I need is something like http://developer.echonest.com/api/v4/playlist/static?api_key=XXXXXXXXXXXX&type=artist-radio&results=10&artist=miles+davis&bucket=id:spotify-WW&bucket=tracks&limit=true

With how ENAPIRequest takes in parameters, how do I include both bucket=id:spotify-WW and bucket=tracks? Is there a way to do that? A work around?

Thanks
