Create instance from random objects

Hello !

I would like to create instance from random objects (all inside a same family of course) and I don't know if it is possible or how to do.

I tried System -> create object "my family" and it doesn't work. I hoped that I can use System -> create object "my family(a random number)" but I can't. (EDIT : forget about my family(a random number), it's based on UID or IID : it's not the subject, just a bad idea :D )

Using array is not permited because it allows only number or text.

Any idea ?

Found it... Just have an instance in the layout for each object in the family.

System -> create object "my family" creates one random instances !

Manual says :

"Create object

Create a new instance of an object type on a layer at a given position. If a Family is chosen, a random object type from the family is picked, and an instance created for that."

I saw the Family part but not the System actions part...

Sorry for that topic !
