Alarm Acknowledgement Handshake to PLC

Adding a property to the "Acknoledge" button on Alarms table to be able to add an expression, opc tag ecc... for handshake the acknoledge to PLC. Many plc program do the allarming control inside and need a specific tag to be high to try the ack/reset of the alarm.

We'd like to enhance this with adding a field in the properties of every alarm to be a "Remote Ack Alarm" field which could link to an OPC item. This would allow that any alarm being acknowledged within Ignition via scripting, or alarm table be also acknowledged in the PLC.

Further to this, there is already "IsAcked" property/metadata for each alarm so all it takes is for this to be linked to an OPC item. Or add a "Remote Ack Alarm" field to enable this handshake for each alarm. This is a very important feature in multiple brand HMI installations where PLC can take on the central alarm management role. Please, please, please make this a feature of Ignition soon. Or if some method exists to accomplish this already, then please let me know.
