Set Product Options prices in one place?

My client's store needs to sell prints of artwork. So all the products will have pretty much the same set of options available, i.e., print size. With OpenCart is it possible to set the option's prices in one place and have it feed to new and existing products? I don't want to have to update EVERY product one by one if the price of a print changes. If there is an extension for this, please let me know.

Thank you.
