Standardize is an amazing function! ... if you know that you won't have any more values added to a column later. With standardize, it's impossible to account for future source values.
It would be super helpful if there were a way to add additional Source Values (and, accordingly, New Values for those source values) to account for values that might appear in the future (but aren't in your data right now).
I realize there are already a number of ways to account for "future" values. Some examples include if...then...else, condition column > case on single column, condition column > case on custom column. However, these transforms are not friendly for those unfamiliar with coding in low-code tools, and this no-code upgrade to Standardize could help these users.
