changing localstream name

Hi dear EvoStream Community and support Team, I need to change the $localstream name or the name under the stream is reachable. For example : If some one passes "MyStreamName" in OpenBroadcaster i want that the stream is reachable under "MyStreamName_1" and not under "MyStreamName". I found a solution by setting stream aliases but the stream aliases only works for one time use. So how can i achieve that? Or what can be a similar solution. thank you for your time and help
