Updating apps stored on a memory stick

I have a firestick 4k. 90% of my apps are installed on an external memory stick. When I install a new app it will go on the memory stick atomically. Can I update the apps on the external memory stick by just reinstalling them over the original install? I currently move them back to the firestick, update them and then move them back to the memory stick. Very time consuming to say the least.

OK How is everyone updating apps that are stored on an external memory stick?

Any sugestions? Something has to be better than moving apps back to firestick, updating and moving back to external memory stick.
