Newbie Needs some help

I have 4 Up2Stram Pros all hard wired with static ip addresses. I have 1 unit set to line in and the other 3 I want to rebroadcast what is heard from the unit taking line in… I have this working now by using the 4stream app and merging all the devices together… Issue is if the power goes out it seems I have to log into the app and start over. Is there a way to save the settings so that they automatically come back after a power loss? I am sorry if this has been covered somewhere else I did quite a bit of searching and could not come up with an answer…

Thanks
