Admin add time limited free trial

[ideatrap]

Request to add the following feature:
Feature: In subscription pricing, allow admin to add user for time limited free trial. For example, 1 year free usage. Currently, it's life time free usage.

Reason: It helps admin to market the product and add seed user. At the same time, give limited benefits to the seed user.

Nice idea! For now you can just add them as a free user and let me know when you'd like to revoke their free access.
