How to switch between hls and progressive factory in playlist

Hi. I am getting lists of urls for audio streams, and some of them are hls.
So I am using this logic, which is suitable for playing separate streams:

val mediaSource = if(lastPath?.contains("m3u8") == true ||
lastPath?.contains("m3u") == true) {

HlsMediaSource.Factory(dataSourceFactory)
setAllowChunklessPreparation(true)
.createMediaSource(mediaItem)
        } else {

ProgressiveMediaSource.Factory(dataSourceFactory)
 .setContinueLoadingCheckIntervalBytes(checkInterval)
.createMediaSource(mediaItem)
        }

To play next/prev stream from notification/lock screen I need to pass list of mediaitems or concatenating mediasource to the player, and I don't see how I can switch between those two factories then.
Maybe with DefaultMediaSourceFactory, but ideally I would like to keep setContinueLoadingCheckIntervalBytes setting.
Is it possible, or should I look into custom actions of notification (i am using PlayerNotificationManager)?
