The only way to solve this is to use the “blueprint way” that btengelh suggested or just temporarily move the pivot (middle mouse button on the pivot + drag and drop)
Otherwise there are also plugins around that will export your objects + they will be at the same coordinates as in your 3d program -> as far as I know there is just something like this for
