Index Column skipping every 8th Row

[roncruiser]

I'm unsure how to index a column by skipping every 8 row.  Maybe that's not even the correct way to do this.

I received some data that's too late to change in terms of a format in the near term.

The parameter column contains stages as indicated by the Stage(Need) Column.  Each successive midp and DQDCC group combined forms a single stage. I need the Stage(need) column but not sure how to skip every n Rows.  In this example it would be skipping every 8th row but some other files it might be skipping every 16 rows.

Any help appreciated.  I'm stumped.  Hopefully it's something simple.

Thank you...

@parry2k 

Thank you for the fast response.  Immediately useful!

I have to study how you modified the index to skip rows.  Not quite sure upon first glance.  I'm getting better at M code but some seemingly simple stuff just stumps me.

Thanks again!

@roncruiser check attached solution, there are few tables, just ignore, take a look at Stage table and it has the transformation steps to achieve the goal, tweak it as you see fit.
