* This means you do not need to hardcode a zaddr in the "from" part of a z_sendmany and/or move funds around from various zaddrs
* To use this feature, use a single lowercase "z" as the "from" in z_sendmany, such as: `z_sendmany "z" ...`
* When using this, funds will be spent from any zaddr that has enough funds
* Note that a single zaddr must have enough funds to make the transaction, funds from multiple zaddrs cannot be used.
* Note that to use `z_sendmany` a single zaddr must have enough funds to make the transaction, funds from multiple zaddrs cannot be used. `z_mergetoaddress` can be used to spend funds from multiple zaddrs at one time.
* Sometimes there are unconfirmed transactions waiting to be relayed to the network. The wallet will resend them periodically but this can be forced with the [https://faq.hush.is/rpc/resendwallettransactions.html](resendwallettransactions) RPC
