Create clustered collection on insert into non-existant collection?

We have an application that sprays data into a collection that rolls over every Sunday to a new name (name contains the date). As in: imps_YYYYMMDD. For various reasons, it is easiest to insert into a collection with a dated name that may not yet exist, and mongodb handily creates this collection on the first insert to the new name.

Is it possible to configure mongodb to create this as a clustered collection?
