Intent number error

Hello? I was using Voiceflow to make English conversation programs, but since the Intent number exceeded 250, I got an error message and failed to upload it. I wonder if Voiceflow supports integration or connectivity between Alexa skills. Could you tell me what options are available?

seems you have so many “simple” intents in choice block, right?

you should use utterances including slots. This is old intenteraction block’s document, now it changed its name to Choice block.
