The BLE component GUI gives you several options to save the entire configuration/profile configuration or service configuration and to use it in future.
For example, you can store a service by selecting the service--> Right click on it--> save. After that, you can add the same service from GATT/Server/Add Service/From file and select the previously saved file.
Similarly, you can save the entire BLE configuration from save icon and load icon as shown below:

Hope this helps !
