Manipular bitrate in Schedule Stream and VOD stream

Good afternoon everyone, this is my first post in the community, and I hope to contribute to it as well as receive contributions. I have a problem using WOWZA STREAMING ENGINE, which I can not find a solution for. The company has a dedicated server hosted at a provider running the wowza streaming engine. Soon I discovered the ease that the server provides with the Schedule Stream tool, where I can stream a list of videos, streaming directly from the server, but I hit a terrible problem, latency. We have a huge latency between us and the provider that is in another country, in order to be successful, I need to manipulate the bitrate with which my list of videos is transmitted from the server (max 3500 kpbs) and there is the problem, I can not find a way make him answer me. What would be the alternatives, considering the following scenario: The final product is played in a player in an app, which is optimized to only play RTMP streams. Thank you all.
