Is there a way to split an existing test case in Jira into multiple steps?

[Akash Musku]

Hello,

we have several hundred test cases in Jira where in multiple actions and their corresponding expected results are saved inside a single test step. Therefore, there is no possibility to set individual actions to pass or fail. I'm trying to split them into multiple steps so that each action has a step of its own but doing this for each test case individually requires a massive manual effort. I was wondering if there is an efficient way to get this done? Has anyone faced a similar problem before and do you have any tips?

Thanks!
