Enhancement on the Multi-Field formula

[Felipe_Ribeir0]

Imagine the scenario where you have an input that has new columns everyday, like the one that can be seem above. But with millions of rows. And you need to build the Total column. This cannot be achieved with the formula tool, because the columns of the input are dynamic. 

Client	20220101	20220102	20220103	20220104	20220105	20220106	20220107	20220108	20220109	Total
0000001	356	223	454	542	827	321	614	759	977	5628

...

The default way that i use and see people using to solve this type of problem is transposing the data/summarizing/joining back the data. I tested this with the Enable Performance Profiling for 10 million rows (workflow attached), and as expected, when you transpose/summarize/join back a large volume of rows, you spend too much computing power. For this test, at least 5x more time than by just using the formula tool (workflow attached):

So, what i propose here is:

1) That the Multi-Field formula could be able to evaluate a set of columns dynamically and generate just one new column (the sum of the evaluated columns, the concatenation of it...).

Example of Designer Discussion that would be benefit from it: https://community.alteryx.com/t5/Alteryx-Designer-Discussions/Transposing-Filtering-and-Summarizing-...

2) That the Multi-Field formula could be able to reference column-1, column-2, column+1, column+2, like the Multi-Row formula is.

Nice Idea, it's definitely a tool many users need in everyday work.
