Emphasis on a region

[Berthold Lorke]

I am talking about this feature:
https://orgmode.org/manual/Emphasis-and-Monospace.html

It currently doesn't seem to be possible to mark a whole region with,
say, "+" to strike through a whole paragraph, especially when separating
each sentence in a paragraph by a linebreak (i believe this is even
encouraged, as seen here https://orgmode.org/manual/Paragraphs.html).

Is there a fix for this?  Enclosing each line with emphasis markers
(like "+") doesn't fix it, as when exported every sentence in a
paragraph would then have a space inbetween the strikethroughs.
