Be able to adjust the duration of a service when creating a template

Usually when secretaries are opening availabilities, when they are adding services, they have the option to modify the duration of the availabilities given.

Ex : even if the service is preconfigured to have a duration of 10 mins, we can still open the same service for 15 mins. ( See attached image)

However, this option is not available when we are adding services in a template, the user will have to stick to the service's initial duration, or create a similar service with a different duration to be able to workaround this.

Users would like to have the option to modify the duration of a service upon adding it in the template.
