The simple answer is "no". There is no hidden checkbox in settings which will do it for you.
Could you post a link to the bug discussion. I think display of repeated fields did not change in the last 15 years.
You can bubble up the values through the script, but I think that you probably need to put your values in a separate related table, where sorting for the display should not be a problem.
That is unless you are talking about printing. I just tried it in 14 and sliding left for repeated fields seems to work fine.
A work around for you would be to show each repeat as a single repetition (i.e., 1 to 1, 2 to 2, 3 to 3, etc.). Then have the repeats slide left.
If it is for printing, in the Inspector's Position tab there is an entry for Sliding Left - this is the one you need to tick to enable sliding.
