Exit and Entry Delay Chirps - Can they be different sounds?

Can we change the chirps so the delayed exit doesn’t sound exactly like the delayed entry? For example, maybe an exit delay chirp could be a beeping souls vs. the entry delay could be a a long continuous sound. It’s constantly confusing when it’s the same exact sound for both exit and entry (especially when we miss the announcement over the chirps) 🤦🏻‍♀️
