Flask stickers (maybe kind of microtransaction) to better spot suffixes

Due to I can reskin flasks (except some problems, see Diamond flask not considered a utility flask?) With this option I can change their appearance to easier spot what’s inside, especially the suffixes e.g. '…of Warding' or '…of Dousing'. Back in combat it is then faster to spot the correct flask and pop it against the current statues alignment.

But this won’t work in all cases, therefore I head two ideas in mind:
__1__ some kind of stickers which can be applied to any flask in various shapes and colors (somehow purchased, maybe not consumable duno)
__2__ the game adds by default certain icons to those flasks depending of their suffix (maybe similiar to the support gem icons on skills)

For one build this might not be really necessary but if someone has multiple it makes it far easier to get back in.
