Gnumeric Solver does not allow decision variables to be non contiguous

Gnumeric solver does not allow to specify decision variables (`By Changing Cells') as noncontiguous ranges. Such ranges can be chosen in the spreadsheet by using the Ctrl key. Actually, in both the normal spreadsheet interaction and in solver I think it would be helpful to be able to select ranges by writing them, as in "C12:G20;C22:G30" (maybe there is such a possibility, but I have not been able to find it).
