A new feature in version “14.08.28.661” of the WholesaleBackup client is the ability to specify distinct backup sets for each backup day
In particular the client has been extended to include (a) straight-forward enhancements to the selection file to specify distinct selections for various combinations of days, (b) a simple extension to the INI file to change default definition for weekdays and the weekend, and (c) a pull-down menu on the Backup->Selections tab indicating which backup set one is editing, and (d) a hyper-text link indicating which selection is being edited/shown with more details available in a popup window when the link is clicked on.

[Everyday], [Sunday], [Monday], [Tuesday], [Wednesday], [Thursday], [Friday], [Saturday], [Weekdays], and [Weekend]. Below is an example of different selections for Tuesday and Wednesday:
