CS6 – Order of numbered lists in a table?

I'm not sure how to do this, and Google hasn't turned anything up.

I have a few tables that have numbered lists in them. Each cell has a numbered bit of text, using a numbered list style.

I want the numbering order to go down the first column, then down the next column, etc. (see below)

InDesign defaults to numbering across a row, then across the next row, etc. (see below)

Does anyone know how to change the way the table cells will order? My solution at the moment is to make the list outside the table, convert list to text, then paste the list into the cells one by one. Obviously this is a pain in the a** way of doing it.

Any help would be appreciated.
