prioritisetransaction - Zcash 4.0.0 RPC

prioritisetransaction <txid> <priority delta> <fee delta>
Accepts the transaction into mined blocks at a higher (or lower) priority

Arguments:
1. "txid"       (string, required) The transaction id.
2. priority delta (numeric, required) The priority to add or subtract.
                  The transaction selection algorithm considers the tx as it would have a higher priority.
                  (priority of a transaction is calculated: coinage * value_in_satoshis / txsize) 
3. fee delta      (numeric, required) The fee value (in satoshis) to add (or subtract, if negative).
                  The fee is not actually paid, only the algorithm for selecting transactions into a block
                  considers the transaction as it would have paid a higher (or lower) fee.

Result
true              (boolean) Returns true
