Currently, there is no good way to "internally link" slides inside Gamma. I don't want to use the Gamma link because I'm exporting out to Google Slides and PowerPoint. I have seen this link correctly by the AI using the Markdown address (I didn't know it was possible to link until Gamma did it on its own, cool!), but being able to drop down and select the slide in the hyperlink would be an easy and great win.
