Ansible Tower Manual Scripts

Hey, I wana ask question that. I have created some scripts into the /var/lib/awx/projects this is the manual directory of ansible tower and the scripts are for REST API CALL for openstack cloud to create instances,group,projects etc.
and the scripts are running fine tower is running jobs and creating the required tasks into openstack. I want to know that if i want to edit some parameters of scripts rather than going to directory and changing that parameters over there. Is there any method by which i can change the
scripts parameter from ansible tower dashboard and than that information is passed into the script which is in YAML format. help please
