Access navmeshagent calculation data?

I have a house with a bunch of doors in it, and I want the ai to be able to open these doors. Currently, the doors open when the ai enters their triggers. However, this makes the ai open a lot of doors that it does not intend to enter and then shutting the door momentarily after passing it. My idea for solving this problem is to check whether the navmesh calculation wants to go through the door on top of the trigger. However, I have no idea how to access the navmesh calculation data. How would one go about this? Or is there a simpler solution?
