In SMBX2 after running the lvl_test_assoc.bat you can doubleclick a lvlx file to run it immediately. Not quite the same thing, but potentially faster.
E: Just checked and you can also drag a SMBX2 level file onto the LunaLoader-exec.exe file in the data folder, which might be more along the lines of what you're looking for.
