New power-up rem: Automatically sort dates

The ‘automatically sort’ power-up sorts any children of a parent rem into alphabetic order. It would be great to have a similar power-up, but which sorts rem according to a date they contain.

I have a document with a long list of rem that begin with remnote date ‘e.g. !!24Jan21’.

I would like to be able to add a rem anywhere into the document and for it to automatically sort into into chronological order, e.g. rem with the earliest date at the bottom and rem with the latest date at the top.
