updating recipes when hops alpha acids change

Whenever I get a new batch of hops and the alpha acids are different I update my inventory and ingredients, but this does not apply the updates to my recipes. Is there a way to update a recipe with the new numbers without clicking on every ingredient and changing it manually?

? I copy my recipes to the Brew Log when I brew, and adjust the alpha acids number when I receive the numbers from the farm that the LHBS sends. Every batch of hops will be differant, and why do a global change every time I brew?
Just my thoughts.
