Is it possible to create multiple sequences with ExtendScript?

Hello

1) Is it possible to code thourgh ES or other, to add a sequence or even mutiple ones? What would be the name/type of variable for a sequence?

2) How to select a particular sequence from 3 sequences you have in your project to add to it a clip (and avoid adding it to the wrong sequence)?

Let's say I want to add clip012 to sequence 012 and clip 023 to sequence 023..

3) When creating/adding a sequence, anything else to consider through coding, such as making sure the length is matching. (I got some alert about that when creating one manually)

Anything else I should know about. Thanks
