Bamboo variable to get the commit of the last successful build

[Fricco]

Hello, is there a variable in Bamboo Cloud here I can get the last commit of the last successful build? I'm building a plan and want to deploy only the last changes, meaning taking from the last commit that was successfully deployed onward. 

Thank you.

I tried with bamboo.planRepository.<position>.previousRevision, but that is the last revision, it doesn't matter if it was successful or not. Any idea of something similar to bamboo.planRepository.<position>.previousRevision but for only the successful one?
