In an Answer to the DOR Petition to Modify Child Support, can I include objections to requested Orders? If so, show ex.?

Example: Request for Order to pay any and all fees, legal costs, etc. Can I object to this in my Answer/response to the initial petition? I have admitted and denied allegations where necessary, and do not object to all Orders requested only those that require further legal argument. If I am permitted to include Objections in the Answer, can you provide a sample of how it should appear? Also, I need to request the Court Order the C.S. terminate at age 18 as it was not mentioned by DOR.
