Merge multiple *.obj files into one big *.obj file (MSVS, c++)

  abaqus, c++, visual-c++

Imagine I have multiple *.obj files like file1.obj, file2.obj etc. compiled by Visual Studio 2015 C++ Compiler on Win64 like:cl /c file1.cpp file2.cpp.
My Goal is to get one big *.obj file which I can pass in Abaqus Subroutine like: abaqus user=bigfile.obj. I do NOT need a *.exe file. Is there any easy linking flag.?
