Couldn't find a solution to go to an specific slide with the native slider so I managed to make it work with some code from finsweet and jquery. The idea is that you can access the slider page with a slider selected by the url. You can test it with a new tab and https://webflow-slider-hash-url.webflow.io/#slide3 If you need a how-to let me know but I put some comments in the Custom code, it's easy.
