mask on zip number + auto calculate

Hello!

It would be possible to do 2 things:

1- Include a mask in the zip code number to make it easier to fill out?
Here in Brazil, our zip code follows the standard 99300-000, but when I type it there in the field, it looks like this 99300000, sometimes people get confused or confused if they typed the full number, because it always has a lot of zeros, there are 5 digits – (dash) and 3 more digits -> 99300-000.

2- After filling in the 8 digits of the ZIP code, would it be possible to trigger the automatic calculation without having to click the button?

Note: there is a Brazilian plugin that does these 2 things above, but I think yours is better to use. (https://br.www.ads-software.com/plugins/woo-better-shipping-calculator-for-brazil/)

Thank you very much.
