Improvement request BE IBAN input field: paste & format

New-Navy-Kangaroo-1227273809

Context

BE IBANs are used in the following format BE12 1234 1234 1234.
Bunq's input field for BE IBANs uses a different arrangement BE 12 34 5678976, and when pasting a copied IBAN in the first input field it doesn't automatically overflows to the other fields.
There's an unintuitive representational difference in the next screen when the IBAN is recognised and is presented in groups of 4 digits.

Issue

Copy pasting is quite necessary for easy transferring money as well as to avoid mistakes and switching apps. In this case you either have to copy paste each Bunq part of the number but that's not supported by the standard.
Typing is more difficult since it's harder to remember and check the number cause its chunks are different.

Request

As soon as the input can default to a BE IBAN the chunks for inputting the IBAN should conform to the default representation BE12 1234 1234 1234 so that it's easier to read and compare (which would be immediately useful for the following screen in Bunq which is currently non consistent with this input presentation)
When pasting an IBAN the inout fields should overflow automatically so an entire IBAN can be pasted in one go.
