I am the first person to HEART this amazing gift? It’s so dang cooool! Thank you Thank you! I have turned the door in a split-2 door, ala Star Trek Turbolift. I hope you might see this? But, is there any way to make the Top level the start level instead of B? I truedd using the Debug checkbox and Level entry, but I can’t figure out whqt it is for (it doesn’t give the option to choose start floor like I always thought,… I guess I will look in the Blueprint for the Letter B? And change that to 23? (MY topmost level) The Bridge of the Enterprise 
Thank you, I am learning so much while learning to use this!
