Can you post a screen capture of what you are trying to do? I haven’t got a clear picture of it from the description.

Is this what you are after?
I drew a small line with no stroke and pasted it as an anchored object at the end of a paragraph. I positioned it using custom options in Anchored Object Options and applied a text wrap that’s at least equal to the column width. When InDesign applies text wrap to an anchored object the only text affected is later in the story. So the wrap won’t affect the text in the current paragraph or in earlier columns, it can only affect the top line of the following paragraph.
Use an object style to consistently format the wrap and anchor options. Copy the object then use GREP to insert it at the end of every paragraph. Use the Find Format option in Find/Change to target only specific paragraph styles.

Thank you, Scott! I applied your technique and it works perfectly; the only alteration I made was to match my leading to the bottom text wrap.
… How do you do between 2 pages?!
