Is it possible to use HSDL for mass update/delete tasks on assigned journeys?

Summary:

Our purpose is to mass delete tasks from assigned journeys without having to do this one by one

Content (please ensure you mask any confidential information):

Hi, we are trying to create a template to mass update/delete tasks from assigned journeys, not from the template. So we tried using these attributes

But instead of removing the task, it removes the assigned journey; note that the attribute Allocated Checklist ID is used to find the assigned journey

How can we remove tasks?

Thanks, Giuseppe
