Can I resize the NavMesh?


In my C++ test project I spawn a varying number of tiles, simple actors with one plane.
I want to adjust the existing NavMesh - NavMeshBoundsVolume - to the number of tiles, i.e. increase it.

Is there a general way to do this?
If so, how do I have to do this?

If not, how else should I proceed?

Thanks a lot for your help.
