Power production graph to remember selection (all merged)

[pistahh]

WHAT

When checking power production by clicking a power pole the production graph shows "All (separate)", even if I changed it before to something else, e.g. to "All (merged)". I'd like this graph to "remember" my last selection.

Alternatively I'd like to be able to configure the default.

WHY?

Especially on Fulgora (using lots of mixed quality accumulators) I only care about the merged values (total energy / consumption), to see how much energy remains. Each time I check this I need to manually select "All (merged)". I'd like to avoid it.
