I would really like this too

I have lots of items with no stock quantity but with residual values (I think due to rounding issue as we buy in another currency)

There are 100s of items clogging up my stock inventory report and I cannot find anyway to write off these sundry values. Show only non-zero items doesn't do the trick as the items have a value (just no quantity).

It is pretty standard to be able to adjust your inventory valuation....  pretty please QBO?
