Nicola Crane commented on ARROW-17779:
--------------------------------------
[~nanimesh] There is currently a ticket ARROW-14415 open to implement this,
though it's not done yet. You'd be welcome to submit a pull request if you're
interested?
There may be other workarounds depending on exactly what you're trying to do
with the multiple datasets. As this isn't related to {{first()}} and
{{last()}} and we try to keep discussions on Jira tickets focussed on the topic
in the description, feel free to open a new ticket with a reproducible example
of what you're trying to do, and we can see if we can help.
