Survey dataset
At the moment the only option available is "iRecord unshared imports" (and if you switch to "Show all options" there are no options available). We need to add an unshared version of the "iRecord moths" survey dataset.

Map import columns
In the unshared imports, the field mapping is working slightly differently to the standard iRecord Import mapping.

For the recorder name, the unshared import is offering two options:

Would prefer this to go straight to the sample attribute Recorder name (which is what happens on the standard iRecord Import mapping).

The imported field "Stage" is not being automatically mapped to the unshared import "Stage (extensive)" attribute. (In the standard iRecord Import I think we have renamed "Stage (extensive)" to just "Stage", and this does get automatically mapped.)
