Currently you can only deselect and select update elements in an order. For example I have 3 recent updates ordered 1 to 3. One being the oldest and first update and 3 being the newest and last update. The current functionality would require me to select item 1 if I wanted to also update item 2. And if I wanted to update item 3 I would have to select all the items before it.

I would like to select each one individual no matter there deployment history. Often I need to do this because the updates have no relation to each other and I might not want to update an environment with item 1 but I do want to update it with item 3.

A quick example is that item 1 is a whole new app but item 3 is a quick bug fix. item 3 needs to be back promoted because it fixes and issue that testing users identified in my testing environment but item 1 cant be deployed into my UAT because then it would confuse testing users and conflict with testing at that moment in time.
