[AccessD] Conditional formatting on combo box

Is it possible to use conditional formatting to change the appearance of rows in a combo box?   Not the value of the combo box, but the appearnace of values in the rowsource?

I'd like to make certain values bold and others normal based on a column's value (not the bound column) in the rowsource as an aid in selecting the correct row (ie, enrolled vs not enrolled).


Thanks
