Reverse sort or add to top for repeating section control

We have a sharepoint list with a repeating section control.

The list tracks cases that are raised. Each case note is added as an additional row to a repeating section.

Some cases can have lots of notes creating a large scroll down the page to get to the bottom and no longer visible is the non - repeating controls at the top of the form.

It would be good to have the ability to change the sort order on the repeating section control.

Basically an add from the top or add from the bottom with the order rows correspondingly ascending or descending.
