Add ‘Last Accessed’, ‘Authored By’, ‘Count’, ‘Created’ to CSV import

Hello,
I’m in the process of importing redirects from another CMS. I have the following content in my export file:
– last accessed
– authored by
– count
– created
Is this supported by your CSV import tool? If not, can this be possible to do so (what would be the next steps)?

Thanks
