syntax help to extract values in desc order

Hi, 

I am not an expert using this syntax and hoping I can tap the brain trust here to accomplish what I want quicker than tinkering with list.sort syntax on my own.  Haven't been able to accomplish with sorting in previous pbi steps.

 

Using power bi, created a table and have grouped it to specifically extract a space separated list of (if your in healthcare) CPT codes.  

 

It's specifically the order I'm looking to impact here.  I've used the following logic to produce field called CPT_pattern and it produces what I want.. as far as the pattern.  For example patterns returned are 

 

90833 99214

90833 99213

 

However I want the field to list the 99214 or 99213 first:  99214 90833. 

 

How do I override the default asc to accomplish what I need?  

 

After a group by I added a custom field= Table.AddColumn(#"Grouped Rows", "CPT_pattern", each Table.Column([Data],"CPT"))

 

This is the step where I extract the values = Table.TransformColumns(#"Added Custom", {"CPT_pattern", each Text.Combine(List.Transform(_, Text.From), " "), type text})

Try this:

 

Table.TransformColumns(#"Added Custom", {"CPT_pattern", each Text.Combine(List.Transform(List.Sort(_, Order.Descending), Text.From), " "), type text})

Brilliant!  I started reading about table.buffer and was hoping there was an easier solution.  You provided it.  Thank you.
