Calculated properties for Products

Looking to autofill the quantity section of the quotes from a property in deals. In specific, our product is priced by Sq Ft which essentially functions as the quantity (cost / Sq Ft).
I’ve looked around for this feature and I’m afraid that it’s not possible as that is a product limitation at this time. Unfortunately, there isn’t a workaround to accomplish this, and I don’t see anything on the roadmap or any current Beta releases to achieve this.
