Hello to all mikrotik gurus

I actually have RouterOS 4.2 in a HP machine basically the main function I have in there is User Manager, in other end I have a RB433AH where I have a hotspot.

I would like to know if I can do this in the User Manager...thi is the scenario:
When I create different types of credits with a specified time like 5 hours and 10 hours for example, is there any possibility to create in the user manager a rule where users that have the credit of 5 hours can use those hours for a period of a month, and the users that choose the 10 hours credit can use the hours for a period of 2 months?

In other words, like setting an expiration date whenever they start their first session, and from that first session having a month or two months depending on the credit the user has?

Thanks in advance for your help

Hi to all

I was confused, I thought the credits time was the time for navigation, and that is basically the expiration date or time, and the uptime limit in the users thumbnail is the time the person has for navigation....

thanks anyway
