Current State:

Currently, when creating or editing a change window, one has to manually select services. The process requires you to manually select affected services, which can indeed be cumbersome for organizations with a large and evolving CMDB, as each new service must be added individually.

Proposed Future State:

It would be helpful if this window supported AQL queries when selecting services.

Alternative (e.g. Third Party Plugin):

No workaround available at the moment.
