Wordpress plugin

Start writing here...Currently, I have a special request. Indeed, i want to develop a feature on a wordpress plugin on a website The plugin is: Restric Content Pro (https://restrictcontentpro.com/) This is a plugin that does subscription management and content restriction on sites.

Currently, it is possible to create subscriptions with free trial, but it is not possible to make a paid trial offer.

For example, it is possible: - to offer a 7-day free trial - which is then linked to a 30-day subscription

It is not possible to (those we wanted to do): - to propose a paid trial of 1 € of 7 days - which is then linked to a 30-day subscription

Has someone have any idea how we can do that ?

Thank you
