Tamplet & Variants Items movement and valuation

Dear Sir,

we’ve created and Item template which has Variants based on color,

when we receive the cargo at the warehouse, we usually receive a large quantity under 1 Variant called mix then do sorting شىي separate the items based on color each under the correct item# … don’t know how to manage this case with ERPNext??

for Example:
Item# STO-24001 is Tamplet

Item# STO-24001-Mix - STO-24001-BLA - STO-24001-GRE - STO-24001-ORG

the warehouse received an order quantity 300PCs put all under Item# STO-24001-Mix then after sorting they found 100 PC under Green , 50 under Black and 150 under Orange,

2nd when do the purchase invoice for the item under the tamplet can we link the new purchasing rate with the valuation rate for the other Variant items under the same tamplet?
