How can I use custom Smackdown 2020 arena parts in Create an Arena?

[Imadulmulk]

I downloaded and installed 2020 Smackdown arena by titavius. I want to use the stage design in a custom arena because I don't like the LED apron and ringposts but when I go to create an arena I only get the old smackdown live parts, despite everything from the smackdown 2020 mod working perfectly including gfx. Is it not possible to use modded parts in Custom Arenas?

create an arena parts are different than the actual stages. you would have to replace parts in pac/arena/arminitron, artitantron, floor, arwall. its not as simple as you may think it is
