Binding to infoblock elements with unique values?

Question

PHP

Hello!
I have an infoblock with cars, I bind characteristics from another infoblock, but how can I set unique values ​​for these characteristics in cars? For example, fuel consumption, each car will have its own.
Approximate example:
prnt.sc/a0n7f0
Only by standard means.
Help, I've already broken my head.

It turns out that the binding is needed in order to get the values ​​​​of the bound property (for example, the name and something else) and this serves as a text identifier for the characteristic, and in parallel, you need to set the value of this characteristic, right?
Then consider this binding option: the property type in the cars infoblock is String , and in the detailed settings check the box "Display a field to describe the value
"
