Sorry to not reply sooner - there is a way to do what you are looking to accomplish but you will need to go a little deeper than what the default screen in Logicity provides. In short, when you use that schedule button in Logicity all that we are doing it writing out a scheduled Windows task. And after you click OK in that Window it asks you if you wish to view the advanced properties- if you click Yes there you will actually be taken to the properties for the Windows task which is much more elaborate than what Logicity provides (we just give the most common options). And, at least on the Windows 7 task scheduler, if I go under the Trigger tab and edit the entry there is an option for 'Last' on the drop-down where I pick which day to run the task on. I think that will be your best bet.
