Microsoft updated Microsoft 365 Roadmap item 561328 on September 11, moving the planned general-availability timing for Access cascading combo and list boxes from August to September 2026. The feature adds LinkMasterFields and LinkChildFields properties directly to combo boxes and list boxes, allowing common dependent selections such as Country -> City without requiring VBA code.

This is a meaningful built-in Access improvement because cascading lists are a very common form-design pattern. The roadmap still lists the feature as in development, so this is a timing update rather than confirmation that every Current Channel user has it today.
