No. They need to be filed separately in ECF. However, if your memorandum of law and supporting documentation relate to both an objection and a motion, you may file the memorandum of law and supporting documentation as a separate document (after submitting the objection and motion individually) using the event Memorandum to Motion and/or Objection. The memorandum of law would be your main attachment and you would link the entry to both your objection and your motion.
