Leather Nato Strap Help

[GM101526]

So I am a first time owner of a watch at the ripe age of 30. I purchased a Rolex GMT Master II 116710LN. I see a lot of images online of people wearing their rolex's with nato leather straps. I really like the idea of having versatility with my rolex and not always having to wear the steel band. Being a newby, I have done some reading on this forum and other sites online and have tried to learn what other people are doing to make it possible to switch out their bands. Please tell me if I am wrong in what I have read.

I could buy a Bergeon 6767-F and remove my steel band on my GMT Master II myself. Then apply a nato leather band that I have purchased. I would use the same Bergeon tool to put my steel band back on? This is easy and quick to do myself? So I could make band decisions based on what I'm wearing and where I'm going?

Who else changes their bands on their rolex often and how do you do it?

Thanks.
