HELP! Mimkatz x86 and x64 in one payload

[Applenuts]

Please someone help?? I am a complete n00b to this stuff, but diving in head first, fast~n~hard. I have successfully compiled and used DK's mimkatz\ProcDump payload. My issue lies in the fact that I have to switch the mimkatz.exe between x86 and x64 manually, depending on the OS. Which implies my inspecting said machine first, then pluging in, swaping files, and so on. Or having seperate .bins (SHIFT+payload button or CTRL+payload button, ect.). Is there a way to have one payload using either .exe version from the root dir? If so, could someone please help a n00b out? THaNX iN AdVAnCE

Maybe you should take a look at my Ducky payload. Its called "ULTIMATE DATA THEIF!!". It should definitely answer your question.
