Affinity Photo for iPad: Sample size larger than 1x1 eyedropper within the brush tool.

[Cantisani]

Please add the ability to set a sample size larger than 1x1 in the eyedropper tool that activates with the modifier button (option I think) within the brush tool in the Affinity Photo for iPad (and Desktop).

This is a critical aspect of a photo retouching workflow, being able to sample the color of part of a surface, not just one pixel. Right now the only way to accomplish this is switching from the brush tool to the eyedropper tool, set the sample to 5x5 or whatever, sample, and switch back to the brush tool and it breaks the workflow completely.
