Using API Button to provide a query/list and passing back into a script

Specifically, I am trying to modify Aura/Tint Health Colors so instead of playing a Random Sound as per the code below, it prompts the DM to select a sound upon a token reaching 0 hp from a drop down list of preloaded sound files -- preloaded with the existing comma delimited format as originally designed. Any thoughts/suggestions/links to something similar I can try to copy would be appreciated. //DEATH SOUND------------ PlayDeath = function ( trackname ) { var RandTrackName ; if ( trackname . indexOf ( "," ) > 0 ) { var tracklist = trackname . split ( "," ) ; RandTrackName = tracklist [ Math . floor ( Math . random ( ) * tracklist . length ) ] ; } else RandTrackName = trackname ; var track = findObjs ( { type : 'jukeboxtrack' , title : RandTrackName } ) [ 0 ] ; if ( track ) { track . set ( 'playing' , false ) ; track . set ( 'softstop' , false ) ; track . set ( 'volume' , 50 ) ; track . set ( 'playing' , true ) ; } else { log ( ScriptName + ": No track found named " + RandTrackName ) ; } } ,

The API itself cant send forms to players or the GM, so the GM would need to pre-choose the voice line via a config setting before it happens. Aura already has a lot of configuring settings - you'd need to create another one for to set which udio to use (maybe it already has one for that?).
