Here is a possible work around.
Suppose you have
myfile1.c, myfile2.c, myfile3.c
remove these from the project and create
myfiles.c
In myfiles.c:
#include "myfile1.c"
#include "myfile2.c"
#include "myfile3.c"
Then add myfiles.c to the project.
Also .CMD file and another files in the project count, so you could remove some of those as well.
