SSIS - How to dynamically update a column table based on DAY OF WEEK?

I need to know if there is a way in SSIS to dynamically update a column in a table based on the DAY OF THE WEEK?

I have a source file that is proceed each day, but it contains one field that is ONLY updated on SUNDAY. So SUNDAY's data file will contain the most recent update.

I need to update my DESTINATION table on MONDAY AM with the data from SUNDAY's PM file.

Then I need to have my package IGNORE the column update for the rest of the week and then update it again only on MONDAY AM..

How can I accomplish this..?

In SQL, the function DATEPART can be used to identify the day

Value 1 would be Sunday by default.
Check this value and do your logic in a Stored Procedure and call that in SSIS

Hope it helps.

Thank you for your feedback..

With that said... is there not a Task I can use in SSIS that will do this? Possible DERIVED COLUMN...or some other task..?

I'm hoping that SSIS can handle the day logic...for the field itself.....?
