Prefix Kv keys with a base part

Currently I add

base()

base()

base()

base() to all keys:

kv.set([base(), "foo"], value)

kv.set([base(), "foo"], value)

kv.set([base(), "foo"], value)

kv.set([base(), "foo"], value)

Instead of manually adding

base()

base()

base()

base() to every key, could there be a way to have it added by default, for all Kv methods?
