beginner Drive object instancing through operator toggles with controllable parameters

[SuperKef]

Hello,

Let me preface this by stating that I'm new to Houdini.

For the purpose of this exercise, I have a simple cube. For the following sides of the cube, I would like to instance a premade object that has its own controllable parameters.

I've set up a folder in my tool with 5 toggles for:

1. front
2. back
3. left
4. right
5. top

Ideally, when I toggle one of these on I would add a copy of the object to the selected side. This isn't the hard part, I can achieve this with a switch node.

What I would like to do is make the object show up in the parameter list with controllable parameters. But with how I set up my network, I don't know how to let the object maintain it's own parameters.

I hope I made myself understandable! Thank you.
