Importing & Exporting Entries/Submissions

I'm exporting a Fluent form & all current entries from site A and importing to site B. It's super easy and I'm very impressed with the process.

One thing: on import the entry with the most current date becomes #1. Whereas on the original site the oldest entry starts at #1 and they count up.

Is it possible (and easy) to import the entries so that the oldest submission is #1 and they number sequentially up from there?
