Cylc now respects the dependencies between tasks when triggering multiple tasks at the same time. This provides an easy way to re-run a group of tasks in order:

This is generally easier than [using a new flow](https://cylc.github.io/cylc-doc/stable/html/user-guide/interventions/index.html#interventions-reflow).

Technical details:

- Prerequisites on any tasks that are outside of the group of tasks being triggered are automatically satisfied.
- Any tasks which have already run within the group will be automatically removed (i.e. `cylc remove`) to allow them to be re-run without intervention.
- Any preparing, submitted or running tasks within the group will also be removed if necessary to allow the tasks to re-run in order.

Note, you can specify cycles, families or use globs to select tasks (e.g. `*/FOO` would select all instances of the family `FOO`), however, at present these will only select [active tasks](https://cylc.github.io/cylc-doc/stable/html/glossary.html#term-active-task). This will change in Cylc 8.6.0 which will open up the ability to select inactive tasks providing an easy way to (re)trigger a family or cycle of tasks.
