Hi Kim Hamann,
One option is to use "Available" instead of "Required" Deployment this way Intune installs it once and the app manages its updates.
Another option is to user Superdense for Win32Apps as it allows allows Intune to handle version transitions more gracefully without manual removal.
There is no literal “install once” button in Intune, but you can simulate this by using detection rules that check for the presence of the app (regardless of version).
