Help with formula to auto create break times

This is a complicated formula, at least not something I can do.

There is an draft attached to this email.

Rules:
First rule is that no breaks can overlap.
1st Break is 40 Mins.
2nd Break is 20 Mins.
1st Break is at least 2 Hours After Time-In.
2nd Break is at least 2 Hours Before from Time-Out.
Each Employee might have a unavailable time for breaks.

Not sure if it is possbile to create a formula like this, or I might need an Excel Wizard to do this.

thanks for any help,

Nick
