New enhancements have arrived.
Template Ratio Control
You can now choose which formats to generate when using a template in Workflows. Click the template node to open a side panel, where you can toggle each format on or off.
Bulk Name Generated Items
The template node now has a new port which you can use to name all the work items generated in one go. This is similar to how Feeds work, where you have a column that is used for standardized naming of files generated using a template.
