Allow background generation of Grid previews for entire albums

Lightroom Desktop currently generates grid previews only for the images that become visible while scrolling. For photographers importing hundreds or thousands of RAW files, this makes the initial culling process unnecessarily slow because every new screen requires waiting for previews to render.

Please add an option such as “Generate Grid Previews” for an entire album or folder. Lightroom could build these previews in the background (similar to how Lightroom Classic builds Standard or 1:1 previews) while the user continues working.

Ideally:

• Generate previews for all images in an album or selection.
• Run as a low-priority background task.
• Show progress in the Activity panel.
• Pause automatically when the computer is busy.
• Store the previews in the existing cache.

This would dramatically improve the culling experience for photographers working with large RAW files (e.g. Sony A1 II 50 MP images) and remove the constant waiting while scrolling through the grid.
