Is it possible to automatically transform a phone number before calling it?

So I want some kind of solution to take a phone number from my call list, contacts or anywhere else, then transform it in a specific way and then add some digits and symbols in front of the number and a symbol after the number, and then forward the newly created number to the dialer. For example, I have a phone number in my call list "+37066611111", if I share it as a number in my dialer app (DW contacts and dialer), I get this kind of text: Contact name: +37066611111 I want some kind of tool to get this text, drop this part: Contact name: +370 Then add additional symbols and digits to the remaining number "66611111", so that the result would look like this: 866622222,789#9#0866611111# Then pass this newly created number back to the dialer. Is it possible? I'm using a bootleggers ROM (Android 9 pie) installed on a Motorola Moto E 2015 phone.
