I don’t think you can do this easily (it’s not impossible though).
What you see in MWS is the result of build & upload from the Designer. But in the Designer you work with source files (.process and others) which you don’t directly have in MWS (*). In MWS you have them in a “compiled” form.
It’s like a source code of a program (e.g. in C) and the executable file produced from it.
(*) It’s not 100% correct, that’s why I wrote it’s not impossible.
