K8056 relay closing time

When channel x is set as ‘momentary’ (i.e. not ‘toggle’) on the remote control K8058, then when pushing and releasing the button x on the remote control, the according relay on the K8056 closes and opens ‘immediately’ afterwards. However, for my application the ‘immediate’ reopening of the relay is too slow. Therefore the question : can the closing time of the relays on the K8056 be shortened when they get a ‘momentary’ command? If yes, how?

Sorry, the timing is firmware controlled and cannot be changed.
