Mobile App: Can we please copy and paste and enter fractions in Amount/Servings like the website?

The cronometer website will allow us to put an entry like "7/8" into the Servings section and will automatically divide it upon submission. The mobile app does not allow this; there is no way for me to enter a / since the keyboard is numbers only, nor does it allow you to copy and paste decimals when you have to divide outside of the cronometer app and return to it.

I would really appreciate it if the mobile app were more like the website in this way. I used to be able to copy and paste in the mobile app but for some reason it was taken away with a recent update.
