Google Translate:
Sorry, it does not make it more clear.
Possibly the term "atom" got lost in translation. In the terminologiy of VaM for example the whole character is an "atom", but it has multiple control nodes for head, hip, wrists, ellbows, knees and ankles.
I'm still not sure whether you want to animate between different poses or are fine with instantly snapping to a new pose. In the former case you will need to look at IdlePoser plugin or potentially also Timeline. In the latter case, you could just use PosePresets, which just save/load the current pose of a character.
