Move "Skip/Include package" to the Create release page
In most cases, when you create a relase where NOT all steps(packages) are included, you wish to deploy the same steps to multiple Envirnoments. Today you have to select these same steps for each environment you wish to deploy to.
By moving "Skip/Include package(step)" to the Create release page the number of necessary clicks will be reduced, and it will be easier to see what is deployed in the different environments.

Good suggestion. We perform what we call "micro releases" where we deploy a subset of our normal release. The amount of manual clicks to include/exclude correct packages for each new version and deployment is a big source for manual errors.
