Completely overriding Haxeflixel Executable Icon

[Raltyro]

Is there a way to 100% override haxeflixel default exe icon with only one image?
or you just have to do multiples of "" with different sizes?

or atleast, how to forcing the executable icon to use a different existing ico file

add the following code in Project.xml:
<icon path="assets/path/to/your/image.png" />
