Group Output Format Settings - Summarise Group Total on quote template

Sometimes it would be great to have the majority of qroups expanded on the quote (all line details shown) but consolidate a couple of groups into one line. Can there be a switch within the Group output format settings to achieve this.

Use case examples....

You need to detail all of the consumables that may be used on the job to work out the pricing but just show it on one line as 'Containment £XXXX'

Or you may have a detailed labour breakdown for quoting / budgeting purposes but only want to show one line as Installation Labour £XXXX.
