Hey there, @jackie_therainmakerinstitute.
Thanks for following the thread and sharing your concerns.
When using a third-party importer tool as mentioned above, you'll need to discuss the details of importing with that third party. The third-party tool that you use would have the information about the tool and how it works, I recommend contacting them to gain some insight.
In the meantime, please let me know if you have any other questions or concerns. I'm happy to lend a hand. As always, feel free to reach out to the Community any time you need assistance. Have a great day!
