Are there any plans to add this to HS?
It is easy enough with most carts to create a product with multiple options, lets say a M3 Bolt with size options of 10mm, 20mm, 30mm and skus on each option for stock control. But as soon as you want to create a 'Kit' that has 25 M3 10mm bolts and 6 M3 30mm bolts, 3 50mm x 5mm x 500mm aluminium plate etc . . . . no cart except for the expensive ones can do it. There are always exceptions like you cannot add a child product to a kit if the child has options (forcing you to create a separate product for each of the bolts etc (10,20 & 30mm). Volusion, shopify, and all of the other carts cannot do it.
How about it HikaShop? Kits as an extra module (like the serials) or included as part of the Business package.
