On desktop you can select a certain number of open orders and export simply to a csv - really useful.

We now use Identifiers however these do not show on the Open Order export which makes them purely a visual processing aid

It would be really useful to be able to export them in the Open Orders export.  Appreciate they are unique so can see hurdles but still very useful

This is a good idea - it could be added as a field in export data under settings as open orders and open orders beta (in .net) don't seem to have an export option that I can see. 

If you are interested in my suggestion to add an action type to the rules engine here is the link: https://help.linnworks.com/support/discussions/topics/7000040549
