I think currently Sentora is facing a major tecnology update that wikll helps to adapt everything to nwewst PHP versiones, and another functionalities. If you are looking for functionalities that will not be implemented for Sentora in a short period of time probably your best option is to migrate your cpanel clients to another cpanel account in another hosting provider. Maybe you can look for a provider in your country or in another country where your currency is more valuable.
Sorry for my bad english, I'm just a enthusiastic learner.
