Help for Aimeos

I play something with your packages it greet but i missing something or i did found yet.

I sell parfume in my shop i need this:
Parfume 1 options
30 ml price €25 stock 10
60 ml price €45 stock 5
90 ml price €75 stock 3
Total stock 18 (stock on product)

Parfume 2 options
30 ml price €45 stock 5
60 ml price €75 stock 3
90 ml price €125 stock 3

So is it posseble to give the option 30ml by each product a other price i did find a field for it.
And is it posseble to give each option different stock value.

also i need one field by product soudlike suggested retail price
Example the suggested retail price is €60 i give 10% discount so the sell price is €54 I found the discount field and price field but not the suggested retail price

It this al posseble todo it and doe you have a example of it.

Create products of type "Selection" and add variant articles to them. The variant articles can contain own prices and stock levels and are exactly what you want.
