[Other Question] Choosing next battle transition

[Vxpor]

I saw Mej71's and FL's comments on setting battle transitions, but their methods are outdated for v17. Is there a way to adapt these methods for version 17? I really like the idea of making a switch for calling transitions or just assigning them to the Pokemon themselves. I am also currently using EBS and you can do sorta the same thing with the "Minor Legendaries" part of the script, but there's only one animation and it is not what I'm looking for. Any help for this is very appreciated.
