Individual Creative Cloud subscriptions should be universal to every Creative Cloud product
For my enterprise I subscribe to multiple individual Creative Cloud products (for users who need 1 or 2 products only, since it is more cost effective than an All Apps subscription). I might have 9 of 10 PhotoShop subscriptions assigned, 10 of 10 Illustrator subscriptions assigned, and 11 of 10 InDesign subscriptions just assigned. That means I have to true up InDesign by 1 even though I overestimated my PhotoShop and am 'overpaying' until I am allowed to true it down. All individual subscriptions cost the same, so Adobe should allow me to transfer quantities between products (so I can just reduce PhotoShop by 1 by transferring it to InDesign - bringing InDesign up to 11). The new subscription model is already working in Adobe's favor - the least Adobe can do is provide more value to its customers by creating flexible subscription controls like this.
