It is possible to store pointers into data structures arrays, and get these back with a "get" or a or an "array get " ?

@Il-pleut I do not think it is possibly, but perhaps I am wrong and it is worth a try...
But, you can store pointers easily into a list: https://forum.pdpatchrepo.info/topic/11435/access-pointer-with-list-store

@Jona thank you. A methode do do it without getting out of the datastructure world would be awsome but maybe it is not possible.
