The import mapping feature is a one click function that automatically saves the matched columns of a guest import file. The file mapping is saved in your Account area under the heading Import mapping.
​
All saved mappings are available via the Saved mapping drop down on the Import page, so the next time a file using the same formatting is imported you can simply select the saved mapping from the drop down and upload the file in one click, bypassing the entire column matching process.
