Change array to include new cells

I am having a ton of trouble with this. I am trying to add a single text row in between existing data. I have tried multiple loops to try to place an array into Column G, but I cannot figure it out. Is there some coding that will produce the sort of result below in column G?

Col E	Col F	Col G
		
a	1	a
a	1	a
a	1	a
b	0	SUMMARY
b	0	b
b	0	b
b	0	b
b	0	b
c	1	b
c	1	SUMMARY
c	1	c
c	1	c
d	0	c
e	1	c
e	1	SUMMARY
f	0	d
f	0	SUMMARY
		e
		e
		SUMMARY
		f
		f
		SUMMARY
