[FEATURE REQUEST] Option for customised filament preheating

[brunofresco]

Printer type - [Prusa XL]

Is your feature request related to an existing problem? Please describe.
Because I sometimes use different filaments, I always get errors that the correct filament is not loaded.

Describe the expected functionality
There should be a functionality to add custom filaments to the preheat menu and name them, or when it is time to preheat to load a filament, a function called "load custom filament".

There's already a PR for that: #3657. However naming them individually won't be possible with the current state of the firmware.
