execute SSIS even when source is missing

I do have a SSIS package which includes 3 dataflow-events, two Imports from Excel and one flatfile-source. All works fine. I now experienced that one time, the .csv was missing for the flatfile-source because it was deleted by mistake. two day later I noticed that the full package was not executed because of one missing file of three. Is there a way to let the package run even when one source is missing? I have the three dataflow-events packed into a sequence-container.
thx for any Input

Set DelayValidation on both the source and the connection to True, and add task in the beginning to detect whether the file is there or not, and if no exit the application with no error / some kind of message.
