can i upgrade(increase) Cloud storage of Adobe CC?

like subject, can i upgrade it?

i asked it before thru 1:1 Chat Ask(idk what its called in English) , but they said you can't upgrade or increase even you pay more. but is there really no ways to upgrade or increase?

i don't mean i want to upgrade for free. but 20GB is too small for me. every single my works are over than 0.8GB . even i emptied my archive.

i can pay more.

i tried using double account, but there is a problem that i can't log-in on the same time.

please help me.

and sorry for bad english.
