Happy New Year!

I have a client who ships exclusively via UPS.
She would now like me to set up the following (and I have no idea how ;)):

For Signature required charge $2.50 - All categories of shipping

Add $2.00 to UPS fee to all Next Day Air categories and 2nd Day Air

Handling Fee - $5.00 - this is just for the Next Day and 2nd Day categories.

I had previously added a handling fee for the UPS module, but how am I supposed to go about this new additional request that only applies to specific types of UPS delivery?

I know I can add an option (using a clone of maybe some other ship module) to check the box for signature required and attach the $2.50 charge that way. But not the individual handling fees for Next Day/2Day.

Any assistance or advice would be greatly appreciated!!
