Suppress Printing of Invoice Comment Lines if blank

SUGGESTED

Thank you for your attention.

I have an Invoice Report which has a Data Field that retrieves Invoice Comments (line 1 & 2), however I would like to create a conditional filter/format so that IF either of the Comment Lines are blank, the relevant Field is suppressed and the space afforded it on the report is freed up/used by the next entry.  At the moment, if the Comments are blank, the report allows 2 extra line spaces as blank entries.

Is this possible?

I hope I explained this sufficiently.
