Do your sound sources and video sources have the same timecode when recorded on set (jam sync to time of day)? If so, then no need to make a sequence – just select all clips and do AutoSync based on common source timecode.
Subclips always have a relationship to the master clips. If based on tape name and timecode, then those will be the same on your master clips and subclips regardless of what you choose to name the clip. More detail on how and what you are conforming will help answer that one more completely.
