I don't know whether this would be possible at all, but it would be great if existing build steps within a job could be easily wrapped with a condition. Currently, the build step needs to be re-created within the condition, which is a tedious task for complex build steps.

Maybe this could be implemented by adding a "Copy existing build step" entry in the "Builder" combobox, and this would then come up with a list of existing build steps in the current job, allowing to choose one, which is then copied with the exact same settings as the original.
