I could give you 3 lines of code that do the job, but my suggestion is that you record your own macro while:
-start recording the macro
-select the input area (G7:M7?) and Copy its content
-select the first free line in column C
-execute paste-special /Values only
-press the Esc key
-select G7
-stop recording the macro
Then if publish the code we will make the modification to fill not that specific row but "the first available"
