Multi Row Formula Multi-Conditional Statement

[D_Constantine]

I don't think that the multi-row formula should be that difficult to put together but I'm a little stuck.  Below is what the data looks like now.  

C1	C2	C3	C4	C5
Internal	SYSTEM FOR ESTIMATING	A10322	0919-175	Brooklyn
Internal	SYSTEM FOR DEPTH	A10333	0919-176	Brooklyn
External	SYSTEM FOR DEPTH	B10223	0919-215	Brooklyn
Internal		B11458	0919-177
Internal	Garments	C20459	0919-178	Pittsburgh
Internal	USING garments	C20562	0919-179	Pittsburgh
Internal	USING garments	C20562	0919-180	Pittsburgh
External		C20562	0919-211

I would like the blank spaces in [C2] and [C5] to fill what is above it, only if the letter/number combination in [C3] agrees to the one above it.  If it does not, I would like the cell to stay blank.  I'm getting lost writing my formula because of the dependency for [C2] blank cell and [C3] same row as blank cell has to equal C3 row above blank cell.  This is what I put together so far.

IF IsEmpty([C2]) AND [C3]=??????
THEN [Row-1:C2]
ELSE [C2]
ENDIF

This is what the outcome should be.  

C1	C2	C3	C4	C5
Internal	SYSTEM FOR ESTIMATING	A10322	0919-175	Brooklyn
Internal	SYSTEM FOR DEPTH	A10333	0919-176	Brooklyn
External	SYSTEM FOR DEPTH	B10223	0919-215	Brooklyn
Internal		B11458	0919-177
Internal	Garments	C20459	0919-178	Pittsburgh
Internal	USING garments	C20562	0919-179	Pittsburgh
Internal	USING garments	C20562	0919-180	Pittsburgh
External	USING garments	C20562	0919-211	Pittsburgh

Thanks for your help!

Hi @D_Constantine 

See WF attached. 2 Multi-Row Formulas should do the trick.
