Merge two creative cloud plans to one

Hello

I currently have Premiere pro single app plan + photography plan.

Since I want to add after effects it would be convenient to get rid of the two plans and create a new one (all apps).

Is this the right way to do it? Profile page does not offer any type of explanation.

I started to cancel one of the plans and got to a point where i was notified that when i cancel early (i have yearly subscription plan) i have to pay fine???

help is much appreciated, thanks.
