Formatting

Is it possible to format part of an expression?

I have an expression:

=(Fields!Intervention_Date_Of_Service.Value & vbcrlf  &  Fields!Intervention_Comment.Value &  Fields!Intervention_ID.Value )

I would like my report to display Fields!Intervention_Date_Of_Service.Value underlined

i.e.,

"4/6/2015 12:45:00 PM"
