How can I customize the Meta+[Number] shortcuts in Plasma?

Hi all,

I'm a longtime Windows user and I recently switched to Debian. I'm curious if there's a way to customize the keyboard shortcuts in KDE/Plasma to behave a bit more like they do in windows.

For example:

1. When using the Meta+[Number] to activate a task manager entry, is there a way to change the order that they are opened?
   In Windows, if I have 2 Firefox windows open, Meta+[Number] will always open the "first" Firefox window, unless I keep Meta pressed and press [Number] again.
   KDE, however, will always open the Firefox window that was last used.

2. Is there a shortcut to open a new instance of a window? For example, something like Meta+Shift+[Number] to open a new Firefox window.

I'm using KDE Plasma 5.27.5
