We have a project that needs to track the number of subtasks on an issue by subtask type. They would like to see 'counter' fields on the issues that increase everytime a new subtask is added to the issue.
Issue A
Subtask B Counter Subtask C Counter
Subtask type B is added to Issue A - Subtask B Counter increases to 1
Subtask type C is added to Issue A - Subtask C Counter increases to 1
Subtask type A is added to Issue A - Subtask B Counter increases to 2
Any idea on how to get these counters
1 - on create
2 - by subtask type
We are JIRA v6.0.2
