I am sure it is possible via scripts or Actions, but you have to make those action routines yourself. And yes, it will involve rendering and such, making a backup copy first, overwrite, etc. Then you can assign every action list to a button or hotkey. It is quite specific for the task you do, so you have to do it yourself and it might take you quite some time preparing all this + testing + fixing + special case scenarios, etc. The probably you woul dwant this Workflow\Workspace to be available as a Screenset (it is a Reaper UI feature) with all the buttons and panels the way you work. Once done, then it can be extremely fast workflow.
