Multiple languages and Emoji button on iOS keyboard

I'm using German and English keyboard on my iPhone and want to insert emojis easily. The problem is when you have 2 languages and emoji, it only jumps to the next keyboard. This is very annoying.

Is there a possibility to have a language button (German/English/…) and a emoji button?

No, this is not possible.

You can quickly switch to a specific keyboard by holding down on the keyboard language button and sliding your finger to the specific keyboard.

Also, the keyboard order is always fixed, so you know to double-tap the keyboard language button to go to a specific keyboard from another specific keyboard.
