Is there a way to change the mash efficiency on a per recipe basis? If not can this be a feature request? My use case is this: my brewhouse usually gets a mash efficiency of about 89%. However, when I brew really high gravity beers (e.g. Russian Imperial Stout - OG=1.113) my efficiency goes down to about 80%. I know I can go in and change my brewhouse efficiency but that changes it for everything and it's a pain.
