How do I sort my conditionnal formatting rules?

I have a very complex spreadsheet with well over a hundred conditionnal formatting rules. I need some way of sorting them in case I need to modify one. Is there a function, or possibly an addon that will do this?

I would need to be able to organise them according to the following criterias:

-style to be applied

-selected cells (only show me the conditionnal formattings that apply to the selected cell range)

Thanks in advance
