Bold Part of String in Crystal Reports

I have created the following formula in crystal reports: "Issue: "+{Issue.Summary}+"  Action: "+{Issue.Action}.  The formula puts the labels of the items in front of the string.  I need to bold the words Issue and Action so that the reader can see where the new thought begins.  I cannot figure out how to bold just the two words Issue and Action.

Also, it is possible to create a new paragraph in the formual for action.  The length of the summary can be different for each individual issue.  That is why I built the formula to concatenate the two items together.  Any suggestions would be appreciated.
