Where should I keep my hiking poles when not in use ?

I have a Kawka 55L and will be hiking the Pyrinees with Z poles that i usually keep on my hands but how do you all attatch them to the bag? Do i need to mod it or is there a nice place to keep them? Each lateral pocket holds a bottle of water (1L) but it feels like they should go in the tall lateral pocket. Not sure how this will impact durability if i store them often. Any advice will be helpful. Thanks
