I wish I could Import data to the Parent sheet and the Subtables using the same file at the same time, without having to do it in two steps.
For example, I have two sheets, Sheet A and Sheet B, that is referenced in Sheet A as a subtable, if I want to import data for those sheets I would need to import first on sheet A and then on sheet B, it would be good if I could do it all directly from sheet A, so using a single CSV it would create entries on sheet A and subtable items that would become entries on sheet B.
