Compare: select by dynamic zone name or user text

[YaLTeR]

I'm using dynamic zone names and user text a fair bit. For example, I have a zone for ClutterActor::allocate() where I get the concrete ClutterActor derived class name at runtime and set SomeSpecificActor::allocate() as the dynamic zone name, and put it into the user text too. Or, I have a zone for JS::call() that runs a GJS callback, and I get the actual JS function name about to run and put it into the zone name and user text.

When comparing it would be useful to filter by this dynamic zone name, or alternatively by user text, to narrow down the specific type of the zone. But so far it seems that you can only select by the source location and static zone name:
