No. But with one eraseblock you can't get much wear levelling anyway.

It might not be too difficult to write an application that appends 
new data to existing data to the partition, erasing the whole block when 
it fills up and write the latest. Then you need something that will search 
for the latest version of the file. Something that jffs2 does, but on a 
smaller scale, acceptable for your application.
