New feature request for Snapshot

I'd like to request the following improvement for Snapshot:

1) limit the max number of copies in Dropbox, older copies are deleted automatically
2) change name of Dropbox zip files. Now it is I'd prefer
That way I can keep them in 1 destination and delete simply, in stead of deleting in every dir seperate (how else can I keep the snapshots per site apart than putting them in separate dirs?)

Thx and cheers!!
