New subtoken for Formula?

Hi!
We are testing Feed Manager(v1.59) for NOP (3.80).
It's a great tool, but we would need a formula functionality for "ProductCost" field (as it is available for "price" and "weight" in the moment).
Is there a chance to get this in future version?

Thank You and Best Regards,
Ales

I added new subtoken 'productcost'
