Using number bars study and spreadsheet study. How on earth do I add a sub-graph of a specific column from spreadsheet study?

Two possible ways:
1: Add the Moving Average - Simple study, set the Based On to the spreadsheet study and its subgraph, set the Length to 1.

2. Add the Spreadsheet Formula study, and use a formula like this in the Formula field:
=ID1.SG5
- where ID1 is the spreadsheet study.

I prefer the latter.
