Be Able to Bulk Edit Tasks from Different Templates

It is a huge inefficiency that we cannot bulk edit like items on template tasks in multiple templates. For example, I want to bulk edit a value on the same task custom form in multiple template tasks/across multiple templates. I pull all of the tasks in a template task report, select the several I want to change, all of which have the same task custom form, and you cannot do this. You get the error below. You can bulk edit tasks across projects, why can we not bulk edit tasks across multiple templates?
