Hi,
in the map viewer I've configured a feature layer to use an uploaded (custom) symbol for features.
This symbol resembles a flag pole with flag. Thus the symbol's anchor should be on the bottom left corner (flag pole base), rather than the center.
I'm aware I could work around this by adding enough transparent margin to the bottom and left side of the PNG file so that the flag pole base becomes the center of the image.
But it would be better if I could explicitly specify the position of the anchor in the image - is this possible? If not on the web UI, using the Python API would be fine too.
