Hi cruzj,
Currently you can write actions script to move the transition of the workflow based on the input of the fields in the Item Details Tab or completion of Workflow Transition. Depending on the number of fields you want to automate, it can range from simple to highly complex. You will need to activate the action script in the behavior for both upon creation and on edit to have the scripts running with every updates in the field. If workflow, you will need to add the action script to the action script section of the transition.
item.performWorkflowTransition(Transition #, "Comments"); // This is the command line for workflow transition.
