Hey @mark1961! I would think it would definitely be possible to provide something like what Mint uses, however, I don't know if the developers would place that high on their priority list right now. You can always check the 20.04 thread here and see if there is anything like that in development right now.
I'm not sure about this because I run an update script on my system every day as it is, but I do think that there is probably an update notification pop-up window that appears when your system has updates available, similar to how it works in Ubuntu proper.
Someone else who updates from the GUI may have more information than I do on this though.
