Scene alternatives

Hello, I wanted to ask if there's a feature similar to scenes. I’m using an HTML Canvas, so the scene option isn’t available, but I noticed there’s a feature that lets you play a scene when a button is clicked, so I’m not sure why it's not accessible. I’m also worried that making my project too long in a single scene might cause Animate to crash. I'm fairly new to Animate, so I’m not familiar with all the features. Are there any alternative methods or tips you could suggest?

Thanks in advance
