There is no workaround that I know of to the limitation you
correctly noticed.  python.exe (or the python executable, on
non-Windows platforms) would have to be modified to remove
this limitation (or, to put it the other way 'round, to add
to it some presumably-optional feature to search for the main
script along some kind of 'path' -- presumably only if the
main script is supplied as a bare filename bereft of path
and such a named file is not found in the current directory).

If you want to write down the specifications for the new
requested features, it could go into a PEP -- don't worry
about implementing it, that will be easily done if the PEP
is approved, but rather about the pro's and con's of the
proposed enhancement.  Biggest pro I can think of is that
people ASSUME the feature already exists and are surprised
to find out it doesn't -- therefore, on the principle of
least surprise, I guess it should go in, unless some serious
contraindications should emerge...?
