Compile setting to delete/customize lines between paragraphs

I like to write leaving blank lines between paragraphs.

How can I make a setting in the compile options that would remove those extra blank lines when compiling, or better yet … give them a custom line height so I can make them compile at about half the normal line height?

(somewhat of a newbie wading through the compile options)

I’d remove the empty paragraphs and add spacing After the remaining paragraphs.
