some of the mods on pcalc discord know how to do it but currently according to zak pcalc is missing some needed things so that has to be updated I assume + a guide needs to be written(according to one of the pcalc discord mods) before its able to be done by the public
auto
no cause citra can't...
it fidgets if you dont move your character, yea you c an skip the fidget box by just leaving it at 0 or unchecking it. the custom delay if thats what you're talking about is different on each save and is save related.

edit: please don't follow any other guide for wormhole things (besides xurkitree/nihilego those are somewhat stable and still being worked on) this guide has been approved by the developers of pcalc
that post is 100% up to date, extra noise on nihilego so its unstable, xurkitree is unstable cause of noise as well(lightning + running around xurkitrees as well)
