the results will total all dice pools so you will get the sum value if you try to roll it all at once.
BUT if you enable the “show pool values” option, each dice pool’s value will be displayed below the results, you can then roll:
“4d6R{1}L + 4d6R{1}L + 4d6R{1}L + 4d6R{1}L + 4d6R{1}L + 4d6R{1}L”
And see the different values (ignoring the main result)
