Import variants with % values from Virtuemart

-- HikaShop version -- : 2.6.3
-- Joomla version -- : 3.5.1
-- PHP version -- : 7.0
-- Browser(s) name and version -- : Chrome 50

Hello,

I have two questions related together:
1) Is it possible to import Virtuemart variants? I followed successfully the import procedure, but my Hikashop products don't have variants/attributes, and VM had it.

2) In some of my VM 1.0 products I had % values that increased or decreased the price, depending on e.g. colour or size. Is it possible to set it in HikaShop?

Thank you
