Massactions in reports are quite usefull, but they only support path transitions.
There are cases, where you would like to apply changes to workflow elements which are in different steps.
For those cases i would be great having the option to just update the element rather than moving to another step.
Background of this idea is a potentially new customer where we have to replace their current mass action functionality (e.g. sending e-mails, mail merge letters).
Adding to possibility to just update/save data would allow to create a new style of mass actions.
When initiating mass action we could then choose an option from a dropdown list and execute the corresponding action by the usage of the workflows global "Upon instance saving" action.
