Target Workflows for Folders within Spaces

My company's projects often require slightly different workflows for each type of project. This is due to project complexity. I would like there to be a feature where you can create a default workflow for a Folder within a Space, rather than just for a Space or the entire account. I find not having this feature currently is confusing for some people and causes issues as we develop the project. Targeted workflows for Folders would help alleviate pain points.
