Some maps are partial or not available in portal - conquest custom

Some maps are partial or not available in portal - conquest custom. Can you please make it so that we can make our custom conquest with all maps and all sizes of those maps. Now we can only make custom conquests with some maps and only small and medium. The BMP-2 and M3A3 Bradley are not available in portal conquest custom. Please update portal to have all the maps and all the vehicles
