Very frustrating that you can’t use node.attach{Text,Image}DataSeries
on a shape that’s in a Mask Group in a repeat grid. You get:
Plugin Error: Target shape node must be in the RepeatGrids edit scope (immediate child of a grid cell or nested only in plain groups)
Outside of a repeat grid, one could probably ungroup, set the text/image data, and regroup to work around this, but inside, there’s no workaround.
This halfway defeats the usefulness of the whole data series scheme, since many graphics in a repeat grid will involve Mask Groups.
