Can we have the option to apply a tracker to weapons that shows all kills that have been made with that specific weapon?
For example, I might have 1000 total kills with Reckless Oracle, but then the rolls are updated, so I want to use a new one. When I get the updated weapon I can select a third or fourth tracker option called "Legacy Kill Tracker" which will show that I have landed 1000 tracked kills across all instances (copies) of the weapon, or similarly would show PvP kills for the Crucible variant.
I believe this behaviour is already possible, as it seems to be available on Momentos, which track kills across all Memento weapons. I think the function could be implemented in a similar way so that reprised weapons could retain their kill count on a new version of the weapon.
