[partly solved]How to store camera positions?

[fis]

Is it possible to make the next functionality:
 - to save the camera positions/viewpoints to the list with ability to add/delete and rename them
 - to save/load the list to/from the external file ?
It would be very useful for the testing the scene, more convenient than simple screenshots.
Please take a look at the video to understand what I mean:

It seems like you can do most of that in the Unity scene editor already... just set up the cameras and save them with the scene. Or are you looking for a runtime control panel to switch between cameras? It wouldn't surprise me if someone in the Unity community hasn't made that already...

Maybe someone already did this using scripting but I wonder if it's possible to make with Playmaker. And Yes,  I want a runtime control panel to switch between camera positions,  but not cameras. Camera should fly from one position to another when I select this position stored before position in the list.

This is what I have managed to create for this moment:

and source (require playmaker installed ):

I don't like the way it works. If anybody have an idea how to store viewpoints and fix camera movement more closer to the way in the video above you are welcome.

I will continue to share my research results in the next topic:
