gtk3 icon theme per application settings

Hi, just wondering if anyone knows of this can be done.

I know i you can set the gtk3 theme per application as in below .desktop file, but i want to change the icon theme to match as well.
So for instance, im using the adwaita dark theme globally. But in geany i would like the application to be the adwaita light theme with papirus light icons. Doesnt seem like it can be done, ive searched for a few hours and come across old gtk2 ways of doing it.

snip ...Exec=env GTK_THEME=Adwaita:light geany %F
