Licence subscription

Hey there,

I am trying to do licencing for my personal plugin that I want to sell. Problem is that i need payments each month. Problem is I didn’t find way to do that with this plugin. I tried to combine it with subscription plugins but I dont wanna have new key each month. Is there any way how to achieve this with this plugin? I need to combine licence expiration with subsription expiration. Best way is when I pay my subscription my licence will renew also my licence expiration date. Only function I found to achieve that is to update licence with API or function and calculate new date of expiration. Is there better workaround or any compabality with any subscription plugin?

Thanks, and good work with this plugin
