Spruce Fixed Length Tally Display on EVO

We sell hundreds of "PARENT" items that have 10 associated "CHILDREN" Items. the Children are the items that actually are bought and sold. The Parents do not have any inventory value and only are there to group the children items together. So a 1x4-POPLAR Board is the Parent with 10 available lengths, from 7'-16' as children (1x4POP07, 1X4POP08 etc). When a customer tries to check out in our E-Commerce platform there is no display to the available inventory lengths, as EVO doesn't pull the SPRUCE children data until they attempt to add the item to the basket. To fix this EVO needs to pull the parent/child pricing and data all from spruce once the customer is on the product page so they can see the mix of available lengths from which they can order. Currently the customers are unable to see the lengths and end up just ordering what they want for lengths instead of what we have. This results in a communication train from the warehouse, to sales, to the customer and back again.
