Hi Jolanda,
other than waiting for this improvement, you have a number of other options here :
1) If your module names are specific / unique enough, you can use the search filter to bulk delete entitities of a given module. That already works in the forge component AS IS.
2) Alternatively, you could improve your own installed copy of this component, adding the functionality you need, but of course, future new versions of the component will wipe out your changes. It should only take you an hour to add this functionality, so maybe worth it.
3) You could maybe join the team of people working on this component and help them improve it by having your changes incorporated in the version published on the forge.
