If I'm understanding what you mean by "randomly distributed," I guess you don't want bulleted text to break in the middle of a paragraph and continue in another Text Frame. If I'm right, I suggest you take a look at the "Keep Options" features in the Options menu of the Paragraph panel. Check "Keep Line Together," AND "All Lines in Paragraph."
Make this Keep feature part of your Bulleted Paragraph Style and Bulleted Paragraphs will never break at the end of Threaded Text Fames OR Columns.
