I'm very confused about sending in sat scores/essays

I’ve asked numerous people and they have given me conflicting answer to my question…
Essentially, the question is: can the sat essay be sent from a different test date?
For example, my first sat score was 1440 with 8/8/6 essay.
I’m planning on sending my sat w/o essay from another date (yet to be taken)
Is this possible? Can I “combine” my composite score from one test with essay score from another date?
How does it work?

No you cannot send the SAT essay from a different test date. The UC’s will take the highest score and essay from a single sitting so no mixing and matching.

If you send the SAT without the essay, it will not be considered. Combining scores is known as SuperScoring which the UC’s do not do.
