Nidoru is an Iron Dagger collector. In her short 11 levels of being alive she has smithed, collected and stolen about 100 Iron Daggers.
The Iron Dagger stack is marked as stolen whether in her personal inventory or in a container. I'm pretty sure she has just stolen about 5 or 6 of those daggers (don't get me wrong, she is a thief).
How can I separate the 6 stolen daggers into a different stack of daggers, so Nidoru can have a stack of 94 "legally" obtained daggers?
