In all my attempts to find seat locations, the only known way is to work with global units with moveindriver.. ect. But its incredibly brute force, takes up network usage in MP, takes up needless amounts of resources, and made me cringe when I coded it. Basically, the brute force method does not work locally. The only real way of resolving this is by giving out the commands as doctorsheep said, or forcing BIS and the community to add the selection position names in config.
