Displaying optional fields

I have two custom fields which are optional. At the moment, I’m using the following shortcodes to show them:

Sound Design by [pods name=”podcast” field=”sound_design_by”]<br>
Music by [pods name=”podcast” field=”music_by”]

Is there any way to add the labels (“Sound Design by” and “Music by”) within the shortcode itself so that if the option hasn’t been filled, it won’t display?

At the moment, if I don’t fill in the field, the text still remains which I don’t want.
