Reply To: Typesetting style question

I tried your trick by:
1) Creating a two column text frame.
2) Selecting some paragraphs from the first column and Span-Split it into two columns (including before and after blank lines as you said)
3) Deselecting and re-selecting the text in the Split columns (excluding the first and last blank lines) and making it Span-Single Column.

…well it works, but not in a practical environment.

The trick as asked by Rivkah and as suggested by Obi is to avoid multiple para styles and using one instead. Whereas the trick as explained by you is an extra effort.
