Create a condition for state change for "changing from", rather than "changing to"

[stone hollow]

I'm trying to create a filter on my automation if a state changes, but ignoring if it changes from/to "Unavailable". Creating a condition that a state is "unavailable" is easy (see screenshot), but how do I also add a condition to filter if it changes "from unavailable" ? My device has a habit of becoming unavailable, so just want to filter all state changes that goes to/from unavailable, so I can avoid sending notifications related to it going offline/back online.

not_from is an option for a state trigger. Unfortunately not in the UI but you can add it in yaml (and keep the rest in the UI.
