Features can share a set of tables, and they do so by default.

This can be configured by setting a boolean on the SFT when creating the schema in the AccumuloDataStore.
Accumulo Range class has some helper methods that might let you avoid MIN_START/MAX_END.
Some combination of Range.followingPrefix and the inclusive/exclusive constructors for Range might do the trick.
I think ```new Range(prefix, true, Range.followingPrefix(prefix), false)```
