SSE Networks or SSE plc wikidata for substations

[JohnVeness]

Hi. There are loads of power substations here in UK (https://www.openstreetmap.org/way/938363753) that are tagged with operator=SSE Power Distribution, and which iD is suggesting:

Suggested updates:

- operator=SSE Power Distribution
+ operator=SSE
+ operator:wikidata=Q493854
+ operator:wikipedia=en:SSE plc

However, I wonder if instead these should be suggested as https://en.wikipedia.org/wiki/Scottish_and_Southern_Electricity_Networks and Q43080530 which is a more specific child company of the larger SSE plc.

I'm not sure of the usual way to do things with regards to choosing which wikidata entry to pick, so I didn't want to add this as an issue or pull request yet!
