Silver and Speedberry QoL

**Silver and Speedberry QoL**
It would be really nice to have the ability to make the _berries collected by flags_, as well as the option to _disable them deactivating when you leave the room._

**Additional context**
It would be very useful to have this option for things like multiple silver berries and speed-berries in the same map. More specific requirements for them to be collected and more customization. As well as the ability to not have to worry about them de-spawning if you leave. I'm working on a map with a lot of routes and branching paths that this is necessary for and I was a little surprised that there aren't any options for these berries considering how often they're used.
