Allow optionally creating heading at same indent/level as previous

Use case or problem

When creating a new heading, it’s challenging to figure out the correct heading level (H1 through H6) to stay under the current parent heading - I manually go to the previous heading, make a note of the number of "#"s and type/copy-paste them.

Proposed solution

If I could use Option (macOS) or some way to enter a heading at the same level as the previous heading, that would simplify this problem.

Current workaround (optional)
