Backup settings

Why are these two dialogues different?

The first is from PhotoPaint ~

the second from CorelDraw ~

I don't like Auto-save, I prefer to save as I go. I also prefer to save the backups to another disk, just in case the current working disk goes down.

As you can see with PP, I have the option to not use Auto-save but still save backups to another disk.

With Draw, I don't have this option and I'm forced to use Auto-save Sad .

Can some nice Corel developer jump in and explain if there is any reason why these dialogues can't be the same - and both be as PP?
