Hi Pilou,

> I want replace all the blue cubes!

No problem - on the first replace just do not run the random deselection script so that you will replace all cubes on that pass.

Then repeat the steps for each additional object in the family but do the random deselection script this time.

That should result in a mixture of objects from your family of replacements, but with all original blue cubes replaced, right?
