Activity System Name should be Editable from K2 Five Designer (Workflow)
In K2 Legacy Workflow (K2 4.7 and previous versions), by default, the Activity Display Name and the Activity System Name are the same. If you want to rename the Activity System Name different from the Display Name, you can easily do it as this property is editable.
In K2 Five, Activity Display Name is no longer the same as the Activity System Name. You don't even know what was the assigned Activity System Name unless you have to query it from K2 Database. The System Name is not even displayed somewhere easily accessible when you are building the Workflow from the K2 Designer.
Now, when you use the GoToActivity method from the API, you have to query from K2 DB using the two tables [K2].[Server].[Act] and [K2].[Server].[ProcSet] respectively just to get the System Name of a particular Display Name. Querying the K2 DB will consume additional time just to get the System Name.
I would like to request that the Activity System Name should be editable when building the Workflow from K2 Designer since this System Name plays an important role in many cases in our development.
