Bucket Pattern

Is there a way to keep my buckets from always starting in the upper left? I know I can use the VFB mouse track, but once I turn it off the next series of buckets start in the upper left. it’s a pain for me because when my scenes are heavy up there it gets stuck processing. I know, it’ll have to process up there anyway, but I would like it to stick where I started using the mouse tracker. And, while I am at it, is there any keyboard shortcuts for the VFB tools? If I hold my mouse in the middle of my scene and drag to the toolbar well, the buckets follow it.

In the settings tab you can set how the buckets progress.
