Putting word chapter numbers into endnoe citations

Well it’s time to properly look at writing my thesis and so I am strating with the easy stuff - formatting (or so i thought).

All my thesis is in one document which is made up of several chapters (with section breaks in between)

My currect hurdle is that I am wanting all the reference citations in chapter one to look like: [1.1] [1.2] [1.3] etc, the citations in chapter two to look like: [2.1] [2.2] [2.2] and so on

Does anyone know of a way to do this using word and endnote?

thanks y’all

kind regards,

Beth
