Oracle voting salt

[Zen-44]

Could the generation of salts used in sending vote proofs to an oracle voting be designed such that by having the private key you can regenerate the same salt at a later time?

I think this could be useful for voting across devices and not having to store the salt locally.

Note: I didn't quite understand how salts are generated currently. If the current way of generating them already allows regeneration of the same salt, one should be able to send a vote proof from a device and disclose it from another so it's just a matter of implementation for the clients.
