clear map of collectibles?

Hit a wall in a design and deleted my save to start over, but I really don't want to do the whole collecting everything again, so I'm going to use SCIM to add the slugs/drives/spheres etc that I had.

But, I want to remove them from the game world too. SCIM seems to have a way to do it with right clicking, but that works for about 10 of them and the rest of the time I get the normal right click windows menu.

Does anyone know of a way to remove the collectibles from the map?
