Thanks for getting in touch, Jeff. Not sure I understand completely, where would you like to keep the original name? There are already naming presets that leave the original name in the filename, for example "Original Name + Custom Name + Index". You can build your own presets under by selecting the "Manage..." option in the "File Name Pattern" dropdown. There you can build patterns that contain clip metadata. Let me know if you'd like more details on custom presets, here's a video of the naming basics: https://www.youtube.com/watch?v=zT9HytVHKiU
Note that in the upcoming 1.3 the naming patterns will also be available for single file renaming. It'll be available in about 2 weeks.
I think it is important to have the option when renaming files to leave the original camera file name and just rename the clips via metadata so when importing to Premiere Pro or others you have a useful clip name but you can look at file info and see what the actual clip file name is. Especially useful if you have a bad file and need to figure out what the original file you need to pull from the BU is. And of course utilize the batch rename function, not just rename individual files. Thanks!
