Creato a copy of a collection

[ShabihK]

Hi!
I have a collection with a lot of sprites sheets that belongs to the animations of one character. I want to replace this collection with another at runtime, a copy of this collection but with others sprites sheets. What I would like to know is how to create a copy of a collection preserving all the data (like anchor points and colliders) but pointing to different sprites sheets.
Thanks for your help
