How Fixed Assets Valuation Works?

Hi,
Can anyone please advise how "expenses Included In Asset Valuation"works?

so if i buy a fixed asset and create purchase invoice for say USD500 and need to add freight of USD10, i make a purchase of invoice of freight of USD 50, will the fixed asset be valued at 550 or do i need to perform some other step?
How would system know which freight entry to mark against which fixed asset when entering multiple fixed assets?
and what if need to add more than one expense (say freight and loading charges) to the fixed asset cost?
