In the Data menu, under options for each field it is possible to set the default function to apply for a field.
If "mean" is chosen as the function, is there a way to specify a weighting field, as would be possible when directly applying a function to the field in a table. If not could this be added?
It might be in line with best practice to set this default in the DataManager space, in the Field Organiser block, so you don't have to do this manually after the data refresh?
This is re-classified as an idea, and we will look into adding the feature in 3.0.
