It would be great if we could reassign "placeholder" to unassigned without changing all actions that were already assigned to "unassigned" as well. This way, if a Resource goes on vacation, for example, their future actions will still be with them, while we can assign to "Placeholder" only the actions of their vacation, until we find the person that will replace them. It is also useful when we want to add a new placeholder for a position, but keep a person on the same position on the project. So, if we will have 2 Marketing Analysts and one is still to be hired, but we want to organize their future line, the actions that were already assigned to the first Marketing Analyst wouldn't be a mess.
