Convert UI Assets to Sprites

I have a full set of UI assets - buttons, icons and a one background images - that now need to be delivered as individual PNG sprites. The artwork itself is finished; what I’m after is a clean export so these elements can be dropped straight into the build without extra tweaking on my end...
