You got both.

I have hundreds of SPs, and I have a handful of exceptions. The reason this doesn't come up as a request very often is that it's meant to be, and in practice should be, quite rare.

There's no obvious way to do it in V3, the interface to the attribute encoding interface is very limited and has access to very little of the context of a request.
The new transcoding service in V4 is more amenable to allowing this, but it hasn't been implemented to this point to support that specific feature. It probably wouldn't be a lot of work to add it if a RFE is filed, but the actual configuration probably wouldn't be that improved since you'd have to configure it with an EntityAttribute tag name to look at for the name, instead of just outright configuring the name itself to use as a custom mapping. Some might prefer that I suppose.
