This functionality relies on Condition Templates you need to create first. More information can be found here.
This Condition enables you to use Condition Templates instead of manually adding a number of Conditions to your Workflows. Simply put, Condition Templates are just sets of various Conditions defined by the administrator bundled into one Condition ready be added to the Workflow Transitions.
This method not only saves your time and effort but also prevents mistakes that potentially occur when adding the same set of Conditions in multiple places in your Workflows. It also gives you the ability to globally adjust and change your Template instead of having to update every Condition one by one.
It is advised to use Condition Templates whenever you expect to use similar Conditions multiple times in your Projects.
When adding this Condition you will be presented with a list of Condition Templates you created earlier. Choose one to add it to your Workflow.
Creating Condition Templates is very simple, yet effective and can get very powerful with multiple nested Conditions and different logical operators between them.
The process is practically identical to adding regular Conditions offered by JIRA, so if you're familiar with JIRA workflows it should be an easy task, however, you can learn more about Condition Templates here.
