Pass in feed ID dynamically in Post System Event to Feed smart service

## Feeds
In Post System Event to Feed smart service --> Inputs tab, the input - 'Feed' is expressionable. I have a requirement to pass the Feed dynamically for 2 different departments(Feeds). Can this be achieved? If it is expressionable, how can we pass the Feed dynamically? Because I don't find an option to configure this using a constant !

Any suggestions...??
