Pressure Advance removed from filament setting?

Can you co-exist thou, like if I work through all my filaments and add manual K settings to manual filaments in Orca slicer, will that still “print” with those values? I cant create “True” custom filaments in Orca slicer either , just really “presets” based off “Generic xxyyzz” etc - has no custom filament section like in Bambu

If I setup my custom filaments in Bambu, I cant use Orca - and visa versa.
