AutoCast Cast multiple audio tags from web page

Hi,
Was curious if it is possible to cast multiple tags in order from a web page. Say a page looks like this for example:
<audio controls>
<source src="horse1.mp3" type="audio/ogg">
<source src="horse2.mp3" type="audio/mpeg">
</audio>
Or something like that .. Would Autocast to a device cast horse1 then horse2 etc if cast web page was used?
Thanks for any help! Trying to get local playlists to cast in some fashion
