Jira Align Admins: In Jira Align is there a easier way to delete Sprints that are deleted in Jira ?

[Bhanu Prakash]

As a Jira Align Admin i want to delete sprints that are deleted in Jira.
Navigation steps:

1. Click on Settings Cog.
2. Under "CONNECTORS" ==> select "Jira Management " and select the tab "Jira Boards" 
3. Some of the Boards have a sprint that is deleted in Jira but since the sprint is deleted in Jira, the corresponding Jira Sprint is not automatically deleted. 

Issue: These kind of iterations need to be deleted manually by the admin. 

Question: 
Is there an API to mass delete these kind of iterations 

(or) 
A flag where i can fetch all iterations that are deleted in Jira ?
