[2019] Hi Devs, can you tell us what customisation options there will be for Instant Action please?

I was hoping we might see most of the options we already have in custom arcade such as enemy AI difficulty, enemy team size etc. Also, are there any plans to make this split screen in the future and for us to have a playlist so we can play through the 5 maps?

If you could answer any of these questions u/F8RGE or say we'll have more details soon I would be really so grateful thanks!
