This is possible. Use the -b or -B option.

-b basedir places the snapshot in basedir with a directory structure
that mimics the mountpoint
-B basedir places the snapshots in basedir with NO additional
subdirectory structure

With Netapp/waffle you have automatic hourly/daily/weekly snapshots.
You can find these snapshots in every local directory (readonly).
Example:

framstag@fex:/sw/share: ll .snapshot/
drwxr-xr-x  framstag root - 2017-08-14 10:21:47 .snapshot/daily.2017-08-15_0010
drwxr-xr-x  framstag root - 2017-08-14 10:21:47 .snapshot/daily.2017-08-16_0010
drwxr-xr-x  framstag root - 2017-08-14 10:21:47 .snapshot/daily.2017-08-17_0010
drwxr-xr-x  framstag root - 2017-08-14 10:21:47 .snapshot/daily.2017-08-18_0010
drwxr-xr-x  framstag root - 2017-08-18 23:59:29 .snapshot/daily.2017-08-19_0010
drwxr-xr-x  framstag root - 2017-08-19 21:01:25 .snapshot/daily.2017-08-20_0010
drwxr-xr-x  framstag root - 2017-08-20 19:48:40 .snapshot/daily.2017-08-21_0010
drwxr-xr-x  framstag root - 2017-08-20 02:50:18 .snapshot/hourly.2017-08-20_1210
drwxr-xr-x  framstag root - 2017-08-20 02:50:18 .snapshot/hourly.2017-08-20_1610
drwxr-xr-x  framstag root - 2017-08-20 19:48:40 .snapshot/hourly.2017-08-20_2010
drwxr-xr-x  framstag root - 2017-08-21 00:42:28 .snapshot/hourly.2017-08-21_0810
drwxr-xr-x  framstag root - 2017-08-21 00:42:28 .snapshot/hourly.2017-08-21_1210
drwxr-xr-x  framstag root - 2017-08-21 13:05:28 .snapshot/hourly.2017-08-21_1610

btrfs-snap does not create local .snapshot/ sub-directories, but saves the
snapshots in the toplevel root volume directory.

No, I want in EVERY directory of the sourcetree a subdirectory named
snapshot, example:

framstag@fex:/sw/share: ll .snapshot a*/.snapshot a*/*/.snapshot
drwxrwxrwx  root     root     - 2017-08-22 16:10:01 .snapshot
drwxrwxrwx  root     root     - 2017-08-22 16:10:01 aggis-1.0/.snapshot
drwxrwxrwx  root     root     - 2017-08-22 16:10:01 aggis-1.0/bin/.snapshot
drwxrwxrwx  root     root     - 2017-08-22 16:10:01 aggis-1.0/man/.snapshot

(this is on a Netapp NFS volume)

btrfs-snap creates a snapshot directory tree on a different path.
