Bulk move Test Executions/Test Plans similar to way we had in DC

Description
Bulk move Test Executions/Test Plans similar to the way we had in DC

User friction
Currently, the process is very manual and time-consuming. In Data Center, using Jira’s bulk move feature, it is possible to change the custom field that stores the linked Test Plans or Test Executions. In Cloud, this is not possible.

Steps to reproduce (right now) / Actual Result:
At the moment, the process is done via the UI, but it is highly manual, either by handling issues one by one or by using GraphQL to remove and then re-add the expected Xray entities.

IMPACT

What would improve if solved:
A more direct and efficient way to bulk move Test Executions or Test Plans between issues.

Current workaround:
Either manually using the field in the issue screen or using GraphQL requests to move the data, but it is important to note that this requires multiple steps and careful handling.

Concrete example:
If you need to move a large number of items, the current process requires fetching the entity IDs, performing an API request to remove them, and then another request to add them to the correct destination. While this can be automated with a script, it remains a time-consuming and complex process.
