Did you discover my real objective only now?

Yes it is difficult because the list changes after every addition, so I understand clearly that one may say "look, if you want multiple inserts, use this command multiple times". First simple but useful steps.

For the multiple inserts at once. I do not have a real use case, I only thought that there can be actions done a single time or multiple times (the idea is list processing at once, isn't it?).

Like position, or multiple positions.
Removal or multiple removal.
Swapping or multiple swaps.
Insertion or multiple insertions.
Replacement or multiple replacements.
etc...

I am not sure whether those may be used only in remote edge cases though. And yes one has to stick to a convention, like "the index that are defined for multiple insertion will be used as-is" so at the end is the user that has to care about how it will work.

Like

{ a b c d e } { f g } { 4 4 } -> { a b c g f e}
(sort of stack push)

{ a b c d e } { f g } { 2 4 } -> { a f b g c e}
{ a b c d e } { f g } { 4 2 } -> { a g b c f e}
