'Concatenate' as a Summary Method for Text formatted line item

It would be great to have 'Concatenate' as a Summary Method for Text formatted line item (along with First Non-blank and Last Non-blank). Sometimes, there might be a need to consolidate bunch of text inputs in a line item at a higher level in hierarchy. This functionality would help achieve that. Also, if this summary method is provided, one should be able to select a delimiter for concatenation.
