P: Ability to create grid thumbnails in bulk

Would like the ability to create the grid thumbnails in grid mode outside of generating standard previews. It’s my understanding these are separate 160x106px previews.

This is helpful with large collection - for example after clearing preview file. Right now, the only option is to scroll the grid view and wait for them to populate. I’ve pulled the Lightroom window out to make the window extra extra extra wide to save in having to scroll to generate, but this obviously isn’t ideal.

Thank you!
