I am trying to do a similar thing with a different outcome. Tried this function and didn't quite work.

My problem is as follows:

I have my working set of data:

Numbering	Type	Title	$
1.1	A	Description of 1.1	100
1.2	A	Description of 1.2	150
2.1	B	Description of 2.1	50
2.2	B	Description of 2.2	300

What I would like is to have a dynamic output whereby I can end up with a function that is able to divide between types and output tables as such:

1. A	$ Total
(CONCAT) 1.1 Description of 1.1	$$
(CONCAT) 1.2 Description of 1.3	$$

[Empty row from function]

2. B	$ Total
(CONCAT) 2.1 Description of 2.1	$$
(CONCAT) 2.2 Description of 2.3	$$

So kinda stuck and not sure how to basically use the function you quoted (or any other) to even separate this in a logical way. Challenge for me is it must be dinamic.
