More detail in inventory reports, especially transfers

[Xriuk]

We are receiving a lot of FBA returns, which get sent to a FC outside of our country, and then transferred to it. The way that it is now built the ledger it basically says on a row when the product(s) leave a FC and when they reach another one, but with many products it is impossible to link the "out" and "in" rows of a warehouse transfer without some "reference" to group them.
There is a column "Reference ID" but it's not currently used, at least not for this...

What I'm saying is that we NEED to track down precisely what is being transferred, from where and to where, otherwise we'll lose track of our inventory...
