Ait Tahiti Pass

I'm trying to book a Bora-Tuamotu Pass for my husband and me for the end of July-beginning of August. We would like to travel this way: Tahiti-Moorea-Raiatea-Huahine-Bora Bora-Rangiroa-Tikehau-Tahiti. But in the Internat page of Air Tahiti it allows me to put only 6 flights. In the rules about Air Tahiti Passes it's never said there is a limitation of the flight number. Does anybody know how it works?
Thank you so much

I'm looking at doing a similar itinerary but plan on using Bora Bora as the base for getting to the islands closer to it. I know there is a boat/ferry that goes from Bora Bora to Raiatea (not sure about Huahine yet!)

Could take the easy and frequent ferry to and from Moorea to help the island count. The ferry to Raiatea from Bora Bora also goes to Maupiti on alternate days.

In the end I could book all the flights writing directly to Air Tahiti. The answer arrived a few days later, but everything was ok. I'm not sure about boats, it must be interesting, but much slower. Have a nice journey!
