ADD_DATA from the EXEC collection does not add station data (out of boundary error)

I am trying to add my station meteorology data to the gridded ARL meteorology file, but always fail with a message like: "Station outside of gridded file boundary (lat,lon) ..". However, the coordinates of my location are definetely within the boundary of ARL file I am using. This happens with any kind of global data I am trying to edit: FNL, GDAS or GFS. I just noticed, that if a create my own meteorology with STN2ARL routine - then ADD_DATA works correctly and adds data to that file. I tried both HYSPLIT 4 on Windows and HYSPLIT 5.2.1 on Linux - the errors are always the same.

Hi. The add_data utility is not built to handle ARL files that have a latitude and longitude coordinate system, so it won't work for global ARL files. We will consider adding this functionality into a future HYSPLIT release.

Thank you, Christopher!
This is what was already my impression, but I needed a confirm.

Maybe you can suggest how to proceed meanwhile?
As I noticed, extracting a subgrid from the global ARL file does not help, as the coordinate system keeps the same..
I really need a small region of meteorology data to be modified with my station data, but can't get through this coordinate system issue. If there is any trick to solve it?
