Can't find the option to toggle aim with RMB

I remembered that in the original Borderlands we could change it to toggle aim by tweaking some lines in the WillowInput file

In the remastered version I tried to do the same but nothing happened (RMB still hold to aim), anyone encountered the same problem or have a fix?

Edit: never mind, seems like all I needed to do was to enter the commands at the bottom of WillowInput.ini file - under the [WillowGame.WillowPlayerInput] section, dumb me
