Thank you for using Bitnami. Bitnami packages and configures already existing applications. We can only offer support and help on basic and most frequent application configurations. Always based on the default configuration or on our guides.
If the issue is related to the application itself, probably someone with more experience and knowledge about that specific application can help you better than we can. We suggest you to post your question on the official support forums of the application so others can help you with your issue.
If that's a command that needs to be executed after a specific amount of time, you can configure a cronjob in the machine to run the command
I hope this helps
