unusual requirement for ColumnCombo

I have a TColumnCombo box with 4 columns, one of which is set to zero witch, as it contains a key. I need to have it display the remaining three columns of whatever is selected, but would prefer to have it do so without the info still being shown in columns. Right now, for example, I see this:

5232   Interactive Media                                                      High Wage Potential

The columns are sized based on the maximum length string in each column, and as there is a high degree of redundancy in some entries, I can't reduce the column widths to make the display more pleasing when the list is not dropped down.

Is it possible to achieve this result with the TColumnCombo, or some other single control? Or do I need to use two controls to get the desired result?
