Add a "Run to here" option on paragraphs

Please can we add to a paragraph's settings menu the ability to 'Run to this paragraph'? This would then cause all paragraphs in the notebook to be executed in order up to and including the current paragraph.

Motivation:
When I'm prototyping I often end up with lots of paragraphs at the top of the notebook that I want to keep, then a block of empty paragraphs to provide some visual separation, and finally a set of paragraphs with temporary stuff for testing which I may or may not want to keep.

I don't expect the paragraphs in this last block to work so the 'Run all paragraphs' is pretty useless to me. I just want to run to the end of the last paragraph in the block of paragraphs I want to keep. At the moment I'm forced to run all the 'good' paragraphs manually one by one, which is pretty tedious and also error-prone because it's easy to skip a paragraph by mistake.
