Touch ID accidentally usage

[longthizzz]

so I have touch-id on my iPhone 7, it unlocks,Apple Pay and App Store. But the other day, I was playing a game and I accidentally clicked to buy an in-game app but I wanted to cancel but my dumbass used my finger to close the app and ended up buying the in-game app. I have no problem paying for the app, but my question is can I sent different finger prints to do certain things like my index finger to unlock and my thumb to unlock or is it all in one feature.
I currently have the buying app on my Touch ID disabled

You were holding it wrong....haha..

Not sure about using different fingers, but using a password would be better.

Was wondering this same exact dilemma as well

All one feature for now.

I have both thumbs and index fingers set on Touch ID. If I need to press the Home Button but don't want it activated I'll press head on, or use my finger nail. Not the most elegant but also doesn't give me any unintended activations. Or purchases.
