How to add sounds to favs?

Hi guys, I checked the manual and could not see how to do this.

When using the filter to sort sounds I see there is one called Fav. How can I mark the sounds I like as a Fav sound for quick recall?

Also, I have added some new sound packs and they are now at the end of a very long list of sounds (many hundreds) is there a quick way to jump to the end of the list?

I don’t have an A4 but on digitone you load the patch, then save/export it to the same slot, at which point you can add/remove tags including fav.
Func+turn or push+turn on the patch select encoder should move you through the list quickly.
