Mark as dispatched
'Mark as dispatch' ids a known issue for ebay as they need an initial scan otherwise it's marked as late, but perhaps Click and drop can be amended to allow for choosing what is 'marked as dispatched' on a channel.
For instance I need 'mark as shipped' for tracked items, and that's fine, but not for CRL Large Letters.
At the moment the default is on or off for ALL shipping options. This would certainly cure the problem for me.
