A way to increase co-op experience sharing radius

When I started a coop playthrough with my friend, we noticed that xp wasn’t always being shared depending on our distance(?). Is there a way to modify this behaviour? If anyone could offer some guidance I would appreciate it. I have some tiny knowledge of how to use the asset manager.

Never seen any variables for XP range, don’t think it’s something you can change but I haven’t really looked for it… Though I am pretty confident that I have seen almost every data field in the game so…

well thats kind of a shame. thanks for letting me know!
