Could you please add a option to upgrade just a computing power (RAM & CPU cores etc.) without increasing SERVER'S OWN DISK If I already have enough space available on block storage?

Since most of the time 50GB is enough for logs and operating system operation. After then I just want to upgrade computing power without increasing SSD.

I'm making this suggestion based on this statement:
"once you add a Block storage, the SERVER's OWN DISK becomes unusable for web files, it is dedicated to LOGS and server Operating system only."

If it is possible, please make this feature available.

Also, can you provide AWS Simple mail service(SES) add-on available on your platform? I need this feature urgently.
