If it is all RTMP then you can do it server side using a module that overrides the play command and loads each of the chunks or you can do the same with a custom player by calling the NetStream.play command repeatedly.
With HLS clients are involved there is not a way to do this with just Wowza. As Roger mentioned, you can do it for RTMP clients, as
shown in this guide. This can be accomplished directly in RTMP client with a series of netstream.play() commands.
