Store article variants with a quantity

Hello dear support team

I need help with a setting.

I sell supplements and I use the plugin to offer several pack sizes.

I’m selling
1 x 60 capsules
2 x 60 capsules
3 x 60 capsules
5 x 60 capsules

I can enter a price for the variants, but it’s actually not correct because only one item is put in the shopping cart.

For 2 x 60 capsules, 2 pieces should be placed in the shopping cart
For 3 x 60 capsules, 3 pieces should be placed in the shopping cart
If you order 5 x 60 capsules, 5 pieces should be added to your shopping cart

Can I do this with the plugin?

You can look at the picture where I built the 4 variants.

third picture 3 x 60 capsules
etc…
The prices change – everything is great.

Unfortunately, I can’t manage to put the number of items in the shopping cart for each package.

Thanks for your help.
