Duplicate object suffix (.nnn) to be put elsewhere (prefix maybe?)

The importer I do uses suffix names for import certain stuff; ie: object named “land-col” is an object with collider and “invisible_wall-colonly” is imported an invisible collider); now, my problem is when I do duplicate object blender rename them in land-col.001 and invisible_wall-colonly.001. and that .nnn broke the import feature.

So, I was wondering if I can force blender to name duplicate objects in a different way… ie; 001.wall-col or something alike?
