symbols in dimensions

I am trying to put an depth symbol in a dimension. It is for a hole so I already have the diameter symbol in front of the dimension and Catia won't allow a second symbol after. I know about ASCII values to insert things but a depth symbol isn't a standard character as far as I can find. Is there a way to do this without a separate text box linked to the dimension value?

Thanks.

The only way I know of is to add a second Text (like you said) with a positional link
