[request] QInput Currency or custom mask using Vue filter

I have search other issues and also checked the documentation and also asked in the discord, but I did not find a solution on how to setup QInput to have a currency mask. The currency mask should have the options to set the decimal point character (default: ‘.’) and the thousands-separator character (default ,).

I am not sure how can I achieve this, maybe like this e.g.:

<q-input 
  mask="currency"
  decimal-point="." // default is "."
  thousands-separator="," // default is ","
/>

or maybe pass a callback formatter or a registered Vue.filter like this?:

Vue.filter('currency', (value, options) => {})

<q-input
  mask="currency"
/>
