You are able to make a custom column that would do this.
I found this stackoverflow answer, that indicates a method by checking the exe file how-to-check-if-a-binary-is-32-or-64-bit-on-windows.
For how to do that as a dopus custom column you can check this script that does something similar. real-header-file-type-extension
If you link your account someone might do it for you.
