Using Visual Studio "Build Action" or Preprocessor directives to embed different Resource Files, Different Output Release Folder, and Sign by Script

Question

I have an add-on application for vendor supplied application(APP) (Siemens NX CAD/CAM) with multiple versions.

For each version of the add-on, the build needs a different resource file, different release build folder, and digitally signed with a specific APP version utility.

Currently, I build with different resource files, move the .dll to a different folder, and run vendor supplied Version specific DotNet Signing .bat file on the .dll.

How could I build once for all versions and get all versions?

I'm looking at preprocessor directives, BuildAction properties, and is there a post directive to run a batch file?
