Insert new Tag in Gismo that are not in the list of OSM objects

Hi, I am using Gismo and i would like to import a barrier as a polyline in Rhinoceros.
In the Gismo OSM_search component, however, I cannot understand how I should insert the required tag. From taginfo, the tag I need is: barrier=city_wall, but, if I try to insert it as a string, or separating key and value, etc. it does not work. Which is the correct format for a new tab? Barrier as an object is not present in the OSM object list

Hi @filippo.calcerano ,

Attached is an example how to define a tag not present in the ‘OSM objects’ list.
If something is unclear, please reply back.
