In out game we require heavy avatar customization through virtual goods. So each  player will have their "segments" which will indicate if avatar is male or female and what their eyes, clothes, or bodies look like. But for eyes we have different segments like pupils, eye lids, eye brows, and sclera. My question is on documentation there isn't enough info for me to have nice structured way to implement those. should i try to find a work around or is there a documentation for us to see how "segments" and "properties" on virtual goods work?

What i am trying to achieve is:
Every player will have some item from virtual goods as their avatars.  Clothes, Accessories, and Body Parts. that will make their avatar. And some of the body parts consist of multiple virtual goods. For instance:

 Eye consists of:

  Pupil, Sclera and Eyelids

but Eyelids also consists of 3 different sprites.

Also I want to add some "properties" to virtual goods like wearing it gives you that much of that bonus. and when i reward them i need to calculate total bonuses players has and proceed accordingly.

My problem is. How do I structure virtual goods in a way that supports multiple sprites for one good and can have some properties.

To simplify what i am going to need:

Is there a way to create bundle from virtual goods. and sell it as a virtual good? (it should appear like the brought them individually)
How can I add properties for each virtual goods and once I have playerID get which virtual goods is he wearing and sum the bonuses.

Just to share the work around i've found:

I created meta collection with desired properties and match them with shortCode of virtual goods.
