Avoid sorting when already sorted

[Mario]

I would like to avoid sorting of one column which is actually sorted already.
I have column DATE_TICKET (e.g. 2018-01-01) which is already presorted in previous graphs and YEAR_MONTH (2018-01). SO when I import the data I generate YEAR_MONTH column which is also sorted logically as it comes from DATE_TICKET.
Can I somehow avoid sorting YEAR_MONTH column which is sorted, but just doesn’t have (1A) mark on the column name.

yes you can,
as per the screenshot below this will add the flag [1A] and it won’t actually sort anything.

This small example illustrate how the proper settings in sort and cgel configutation can have a huge impact on processing speed.
