When importing data, often a duplicative relation is created. It would be tremendously helpful to be able to create a Set, and then copy a column of data from a particular relation and then just paste it into another Column / relation.
HOW COULD IT BE DONE?
Unsure about the technical implications here.
REAL WORLD USE CASES
Instead of copying/pasting every individual value from one relation, a user could copy/paste an entire relation.
You mean (in essence) a feature to combine two Relations?
Sounds good.
I think the coming API will give us powers in this direction - all kinds of features for importing/exporting data.
Sort of - however, the nuance is that relations can obviously be related to more items than exist within a set, so if you simply merged two relations, you may mistakenly merge data that is related to other objects not included in the set that is being viewed currently.
