I regularly stream from PS4, and found an issue where streaming certain games causes the category to get changed to "Games + Demos", even though a more specific category for the game exists(Example: Soul Calibur VI). From what I gathered researching this, it seems like minor differences in how the PS4 submits the game category causes Twitch to not recognize it, so it defaults to Games + Demos. The workaround is to manually correct the game category in Stream Manager, however doing this for every stream gets cumbersome, espec as I also have to do it again for VODs afterwards. The ideal solution would be to fix this issue itself, however if this isn't possible/simple(I understand PS4 is managed by a third party), My suggestion is to change the behavior so that if I already have the game category set up before I start the stream, have the PS4 NOT overwrite it. In other words: Set it up so that streams from PS4 will ONLY set the game category if one of the following are true:
- There is not an existing category already set in Stream Manager
- The category submitted by the PS4 was recognized(meaning it wouldn't default to Games + Demos)

This way I'd be able to set up title+category from my Stream Manager all at once before starting, without needing to worry about having to go back and correct the game category every time after starting my streams.
