Subscription renewal dates

We are using the free version.
Now, if a user purchases the same type of subscription multiple times, the start date of the new subscription is the same as the purchase date.
Instead, we would like that if a user purchases the same subscription several times, the start date coincides with the end date of the previous subscription (so the customer renews the subscription without losing days. This problem occurs if the customer renews the subscription during the validity period of a previous subscription).
How can I get this behavior to renew my subscription? If it’s not possible in the free version of this plugin, does the pro version allow you to do it?
