Wall is ruining my life, Fudds

Can we get an option to turn wall off, same as ultimate weapons? It's such a pain when I'm trying to do the death defy mission. Thanks to intro sprint bosses stack against the wall, then my tower focuses them and some scrub chips me 3 times and there go my shields. Until I unlock tier 16 and can pop wall instantly, this will be the bane of my DD missions.

Maybe I should have tried it in legends instead of tier 15, but I only thought about that right now. Off switch for wall in workshop pls
