Sometimes while working in Altru you may want to create duplicate nodes for your export definitions. This can come in handy when you want separate criteria for the same fields in the output of your export definition.
When can accomplish this by clicking on the root node under the export definition when adding your field. For example in the screen shot below you can see that a name format field already exist so if we want to add a duplicate node we would need to click on the root node first:
After clicking on the root node you can then click the arrow pointing right to send the field to the list of selected fields in your export definition.
