Customizing the "Recent Notifications" iView

Hey folks

Our client wants to change the SAP standard "Recent Notifications" iView.  He thinks (justifiably) that the headers "subscriptions" and "subscribed items" are a bit vague, so we want to change them to more specific titles, like "subscription management" and "subscription alerts".

Two questions:

1. Is there an easy way of doing this?

2. If not, how do I customize the iView?  According to the iView properties, it's based on com.sap.km.cm.actioninbox, but I can't find this in a PAR file anywhere...

We're still on EP6SP14.

Thanks,

Chris
