Edit CRM Report Related Module

Edit CRM Report Related Module

when creating a CRM report I am asked to to

1/ choose primary module


2/ and related modules (blue and green + icons represent UI for adding child and parent related modules):



when editing a report after creation, I do not have the the option to change the related modules - I suppose that's by design?

or is there is a way to add / remove a related module in an existing report and I am not seeing it? as far as I can see I can only change its name and description but the initially chosen modules are not editable unfortunately. correct?
