Alp is known for its maps, but is called Alp Maps & Lists for a reason. You can add non-geolocated entries just like you have been adding geolocated entries. They enjoy the same functionality as map entries, except they are viewed in list form.
You can, for example, include non-geolocated entries as part of tours (e.g. history, background, packing lists). If you can put it in writing, chances are it'll work in Alp.
