how to assign custom post taxanomy with custom post type using custompress

I hope everybody is doing ok today!
So My idea was to, use CustomPress to create a custom post type called "Stops" or something similar. This custom post type shall have these three categories called: "Trips, Waypoints Type and Weather.
Before we have been adding a map to the post type, but I think it will be better to use a custom post type.

So I created it and then when creating the taxonomy I can’t assign those to the new custom post type.

Once done I want a map assigned to every new Waypoint created with the geolocations from an uploaded photo or from choosing the location on the map. Then I need a Way to generate dynamic maps showing for every trips taxonomy a single map (showing all locations on a map linked to the article.

I'm happy for every suggestion you can give me.

thank you
