How to change dynamically the output file that changes every month in the gallery server?

[Maricruz]

I'm experiencing difficulty modifying the output file in Gallery-Server. Specifically, I'm unable to select a file for a different month unless it's already predetermined in the server's workflow(where the file location changes every month, and the file name only alters the year and month).

My current workflow Analytic run options(The output predefined in the server's workflow) 

 
The full path of the output file is predetermined in the server's workflow, and I need to change it monthly.

 

Thank you in Advance.
