Multiple Approvals without using transitions or to assign each one of them

Matúš Klaudíny

Hello, 

I've gone through many threads such as: 

https://community.atlassian.com/t5/Jira-questions/Is-there-any-solution-for-multiple-approvals-except-Herzum/qaq-p/75797

https://community.atlassian.com/t5/Jira-questions/Managing-Approval-Process-through-JIRA/qaq-p/667181

https://community.atlassian.com/t5/Jira-Software-questions/Creating-a-workflow-involving-multiple-approvals/qaq-p/686156

None of which was helpful in my specific case. Which is: 
- at a certain status (or in a transition screen beforehand via multiuser picker) to be able to add an unspecified amount of people to 'approvals list'
- to 'lock' the issue in this status until every each one of them approves the issue

without using any additional transitions in between. Is there anyone that has tackled such problem before?
