Add Math Formula Component to Access the EPO element’s value

I first asked this question here: Is there A Way to Make a Variable Global?
https://themecomplete.support/forums/topic/a-way-to-make-a-variable-global/

We're a sauna manufacturer.
Our popular sizes are limited to 4x6, 5x7, 6x8 and almost every combination between 3 and 12.

I'm wondering if I apply EPO elements inside a LOCAL form.
e.g., at the beginning of my LOCAL form, I set these elements inside the starting section

Select box: "Width = 4" (Element id:621be62353ce74.77703845), and a
Select box: "Length = 6"
Can I later apply another section of EPO elements as a GLOBAL form ...

Then in these global elements , I want to base pricing on formulas using the select boxes (W=4, L=6) of the LOCAL FORM dynamically?
I say dynamically because I don't want to do it specifically using a formula like ...

e.g. {field.621be62353ce74.77703845.value} * {Math-Constant-price-per-lineal-foot}
as that would NOT create more efficiency.

Perhaps expanding a Math Formula component that targets the current product's element array and value?

{this.productID.element(1).value}
{this.productID.element(2).value}
... etc

As long as the elements are at the top -- maybe it's workable?

This way I can access the select box setting's of 4 and 6, 5 and 7 etc established in the LOCAL form and use it in formula based pricing for any GLOBAL FORM I add to a product.
