2023x On Premise -Classification Attributes - Utilize formulas to show Calculate costs

Hi All,
We created Classification attributes on 2023x, one of this attribute is the cost of a specific Item. 
My Question is: Can we create a new attribute and utilize formulas to calculate for example the % of amortization or to sum to cost together? (Cost ITEM 1 + Cost ITEM 2) whe would like to use native solution and not customization for this.

Any Ideas or suggestions?
