Update Selection - One Click Update

**Describe the problem you have/What new integration you would like**

When updating it would be nice to be able to select the devices you would like (tick box) to be updated and click a (one) button and it will start the update of all selected devices. Just like the "update All" button but only the devices selected. This way it would be easer/faster to update the devices you would like and not the ones you don't want updated in one click. At the moment you have to update each one individually wait for the update then update the next one and so on. I am sure this would be very useful to everyone and would save a lot of time. It would also making it more user friendly.

**Please describe your use case for this integration and alternatives you've tried:**

**Additional context**

The issue names no files, tests, or entry points. Start by locating the existing “Update All” control and individual device-update flow; done means users can select multiple devices and trigger their updates with one action without updating unselected devices.
