Use Markdown to add Horizontal Line Separator

It would be fantastic if we could use markdown in the mobile app for adding a horizontal line separator. I use this frequently to separate my content.

I find that it is a bit of a friction point to use the forward slash command and then having to start typing the word horizontal just to add a horizontal line separator.

Most Apps (that I’ve used) allow this by typing three dashes.

Even better, in addition to the markup capability, could the same feature also be added to the little shortcut menu that is onscreen in the mobile app? That would also be so helpful.

Thanks so much.
