There are a whack of approaches to doing this.
The filename parameter of the filesink block is runtime changeable.
You could have an external process using controlport or xmlrpc to change
this setting (from a variable) at regular intervals. The existing file
will be closed, and a new one started under whatever name you give it.
Or, you could start with the filesink block, and write a new one that
implements your naming policy as you see fit.
