How do I add a note to a dimension or format dimension text?

I need the gauge number to be bold and attached to the dimension. I have tried grouping a note which hasn't worked for me, I tried adding text to the dimension in the property manager but it doesn't allow you to format bold. I couldn't figure out how to adjust the dimension lines, for this dimension only, to allow me to place the note underneath and not have a line through it. Someone figured this out once, but is now long gone. Please help!
