Allow statistics card to hande multiple entities as statistics-graph card does

It would be nice if “statistics-graph card” would accept multiple entities instead a single one (like statistics-graph does).
Something like the “entities” card but using the configured statistics.

It does. You may just have to scroll down when editing the card to see you can add more entities.

Sorry, I mean “statistic” card. “statistic-graph” card does

If you put in an issue against the front end asking for feature parity (use the term) between 2 similar cards you listed, you may get a favorable response. If presented this way, it is not a FR but rather providing something that was possibly missed during implementation of the other.
Be clear and provide examples.
I would also link your original post here, but provide the information again in your request so they don’t have to search for it.

Now there may be reasons I know nothing about that prevent this, but it looks to me it could be a case of missing feature parity.
