Exporting custom unit from Object Editor

[Footman16]

I have been trying to create a custom AI for one of my campaigns (Will be releasing it here when its done) but I am using custom units for the race and when I secondary click on the unit in the object editor (not manager) I don't get the export option. I get copy, paste new custom etc etc but no export.

I have tried the import manager, object manager everything but there is nothing

Edit:I have posted this in the wrong place lol so could a mod please move it to the warcraft 3 editor help zone
