In Pages on iPad, formatting to add line over paragraph? I’m writing a document with Pages on iPad. When I select the “Heading 3” style it puts a line above the text, like this:

I can't find how to create that kind of formatting manually, outside of the named styles. Where is the option? Here is the part of the screen with formatting controls. I don't see anything to create a border or line above a text block.
AFAIK, you can't add/edit text line styles on i(Pad)OS.
You can edit text line styles in Pages for macOS (Format sidebar &gt; Text &gt; Layout), though, which then carry over/display in Pages for i(Pad)OS.
