2 string inputs combined but shows as different colours

Any chance of having a setup where you can give data for 2 strings say 1 east and 1 west. where the generation graph is the combined total but the colour of the graph is split to show what was generated by the east and what is generated by the west? or different lines for each with a total or something easy to implement?

Each array can be uploaded to separate systems and compared.

There are no plans to allow multiple arrays to be recorded in a single system.
