Feature request: separate setting "Add the image's number to its picture in the grid"

[GlebIgorevich]

When generating batch (not XYZ) the additional information about style and sampler has been added to the grid.
I suggest the separate setting "Add the image's number to its picture in the grid" for two different parts:

1. For XYZ-plot (for showing that only on XYZ).
2. For batch grids without XYZ (for showing that only on grids without XYZ).
