Could you provide an example image? I've never played this game before. Alternatively, you can try designing it yourself using the web demo on Itch.
It's possible to set the position like that, but it will be fixed. Try the demo on the plugin page: run the tool, enter battle, and press 'M' to try designing it yourself. However, please note that the demo doesn't come with pre-loaded images.
Instead of having to buy it first to experience the plugin, almost everyone tries out the demo before deciding whether or not to make a purchase.
