Add system breaks: allow option in dialog to keep existing section breaks

If you use the "Add system break at end of each system" command (Add / remove system breaks" dialog) it replaces all section breaks within the range as well. There should be an option to allow the user to keep existing section breaks (and page breaks?). (see also, https://musescore.org/en/node/316068)
Also, it is not possible to select breaks on the basis of type—i.e. system, page or section—from the selection dialog. Could this be made possible?
