Provide option for key input delay for additional field

[shundred]

An app requires a 4 digit pin. At input it display 4 squares, 1 square for every digit. But when pin is given by keepass2android it only fills 1st square. I can manually press keys on keepass2android keyboard and it works fine. So please provide an option to set delay between key presses for individual fields.

Compare #2064 TOTP: Individual input fields for each digit (example Paypal)

while I understand that it is helpful for users manually inputting TOTPs to make the display large, I consider it a bug in the target app/website if they use multiple fields for entering one value (i.e. the TOTP code), that's semantically not correct. While it may be possible to find workarounds to deal with this, they should fix their input fields (as paypal did).
