Is it possible to store a Scripted field value in Jira cloud?

[Jayanth]

For a Story issue type, I want to track the total time spent in a particular status using a timer. While using a Scripted Field in ScriptRunner for Jira Cloud, I can achieve this. However, if the issue moves back to the same status, I want the timer to continue from the previously recorded value, not restart from zero.

Is there a way to store the accumulated time so that it can be retrieved and resumed if the issue transitions back to that status?

Note:

• I am using Jira Cloud and prefer not to use any third-party apps or add-ons. I am looking to explore the feasibility of achieving this using ScriptRunner Cloud.
• Only one custom field to display and calculate time.

Create a custom field to store the accumulated time and an automation to update it so that you don't lose the data.

Do you have any reference links or useful resources to achieve this?
