Hello!
For ours sprints, we use a column 'Validation' for 2 steps:
- Code Review (CR)
- Story Review (SR)
For CR, others devs go validate my code
For SR, Product's team validate de Task. To this, we up EC2 instance whith especific branch for PO usage, test and validate.
But, we have a bottleneck in SR 
So, my solucion is Automate this Process!
Is there any way to check in Jira when a new task is sent to a specific column? With this Trigger, i can up a docker container with my Task. (And send a Slack Message to productTeam channel - But this is add-on)
Tnks!
