I don't know if this was asked at some point but, if you had started augmenting a delve piece down one path could you stop and have it switched to go down another path instead?
For example if you just started going down a Str path on manibozo feet and just got a skirmish foot piece for the same job. Could you have the npc change the delve feet from atk/str to range acc/atk, even if it ment restarting it back at 0?
