[Koha] Mark a batch of items as missing?

[Mark Alexander]

After doing some inventory in our library, I obtained a list of the
barcodes of a few dozen lost items.  Now I'd like use the batch item
modification tool to change the "lost status" for that set of items.
But I don't see a way to do that with this tool.  Is there another
way?  I'd like to avoid having to mark the items as missing one by
one.  I'll resort to SQL if necessary.

Thanks in advance!
