I'm using an expressoin box to concat the main paragraph title with the content of a second text box in order to get the text to wrap around the para. title.  If I use two text boxes the format doesn't come out as needed because the text doesn't wrap around.  So on my print view I've used an expression value. However, I need to be able to formate the main para title so that it appears BOLD and Underlined.  I've searched and searched but can't find a solution.  Is this not possible.

It should look like this.

Example 1. 

1. (U) Main para. Text regarding the content to the main paragraph
continued text regarding the content to the main paragraph.

If I display in two text boxes I get example 2 but I need the print view to look like example 1.

Example 2. 

1. (U) Situation.  Text regarding the content to the main paragraph
                            continued text regarding the content to the main paragraph.

It doesn't have to be an expression box, it can be a text box or a RTB.  But what I need is for the first word of my text box to appear bold and/or underlined because it is the title for that paragraph.  The text entered into the box needs to wrap around the first (title) word otherwise I would use two seperate boxes and format accordingly.  Is there a trick for this?
