I feel that if possible the devs should give us a crate in the editor which has a check-list of every item available in the game including weapons, ammo, attachments, clothing, every single item. You could then place one crate and check each item you want in the crate (and how many of that item).
If this can be put into the editor rather than having to look up/remember scripts for every item it would be a big help to every single person who makes missions. Even the professional mission makers would benefit because it would save them a big step in complex gear missions.
