I'd like to request an expansion to the setMarkerType (https://community.bistudio.com/wiki/setMarkerType) script command or otherwise a new script command so it is possible for mission makers to more easily customize their markers with a custom .png/.jpg/.paa file (with the correct size of course) located on their mission directory and/or some other Arma 3 location (.PBO) file like the one containing the Task Framework Icons ("\a3\ui_f\data\IGUI\Cfg\simpleTasks\types\") etc. (https://community.bistudio.com/wiki/Arma_3:_Task_Framework).
For example:
"MarkerOne" setMarkerType "\a3\ui_f\data\IGUI\Cfg\simpleTasks\types\rifle_ca.paa"; // Expanding the current Script Command
OR
"MarkerOne" setMarkerTexture "\a3\ui_f\data\IGUI\Cfg\simpleTasks\types\rifle_ca.paa"; // Theoretical New Script Command
Would set this https://community.bistudio.com/wiki/File:bis_tasktype_rifle.png icon for the "MarkerOne" marker.
