"Kronos' Trade Center" Saddle addition concept

Hello everybody. So as many of you may or may not know I’m building an old world primitive mod called “Kronos’ Trade Center” and am looking to add many more immersive and cool feature to the mod, thus I am beginning to branch out and look for more help and/or input. I am starting to plan a new asset that will involve attaching a secondary structure to a saddle at creation. If anyone has any experience with saddles or would like to help/ give input it would be greatly appreciated. If you know nothing about saddles and would be interested in getting involved with the mod elsewhere please add me on steam @ ionic_ovrdose and hit me up. Thanks everybody and happy modding.
