3 Remote Destinations pointing to one destination

[CaseFile]

We have 3 campuses and each one has a local number for a guy who moves between the 3 locations.
He is in the field most of the time, and would like all 3 numbers to call his cell phone, but doesn't want to set forwards so it will ring in his office also.
We have a number of people working with just one number.
When working with Remote Destination, it will only allow me to put in a particular destination number once.
Does anyone know a way to have 3 separate lines ring to his cell phone when his desk phones are ringing ?

You could just create different destination numbers that point to his cell. Though why would anyone want 3 different numbers?

He needs 3 different numbers as each one is local to callers in a different area.
And I am told... It doesn't have to make sense, because he wants it that way.

I tried creating 3 different CTI Route Points as the destination that point to his cell phone.
They work when dialed directly, but not when associated with rdp for a line.

So I was wondering if anyone else had encountered this
