Midjourney Parameters

I use MJ a lot, but I also use many of the parameters. I haven’t found the R1 to be able to use them. Is this something that we could possibly do? For instance, doesn’t the R1 have “Memory” … for instance, if I uploaded a PDF to the Rabbithole or just the parameters, could it then know what parameters to use? For instance, could I say “Make the Aspect Ratio 4:5” and it would know to use --ar 4:5 after the prompt? This would be a killer feature!
