You can file a "supplemental declaration" and/or "supplemental memo of points and authorities" "in support of '[Petitioner's/Respondent's] motion for sanctions."
However, you will have to serve your spouse's attorney again, and the clock for a response is reset. If there is insufficient time available to respond before the hearing date, then your opponent can request a continuance at the hearing.
I realize that getting an actual date set for a hearing with this particular judge may be difficult, but if you already have one, you may want to just go with what you've got.
Note: You may have a valid reason for what you want to do. But, sometimes, when you have nothing else to do buy wait, you start thinking about everything you could have done, and you want to start over -- even though there really may be nothing wrong with your original filing.
Hope this helps.
