Add function in QT project

The result of the marked checkboxes (please see attached pic) should be checked with no-marked checkboxes, so that the TC basic-result can be increased by further single markings. If so, the checkboxes should be remain marked and the higher TC result should be added in the graph next to the TC base-result. This function should start with a button "TC+" and treat the row M1, M2 and M3.
