It's probably just the way the light is hitting it, but that almost looks like a handprint in the top left of the first two pictures in that series.
Considering that Time Team has a new series this topic title seems a bit inappropriate .I'd read that cup and ring marks were actually found under the water, with no references, and spent a fruitless hour following links trying to find out more, and lost where I'd first seen it mentioned.
I saw this about Crannogs in the Orkneys on the Orkneyjar page. Their website is usually updated quite frequently, so I guess they are still awaiting help from the underwater archaeology trust to look into these.

It may have been in the Ben lawers project web site

There was another survey that did find a couple of marked rocks quite near the shore about 4 years ago ,(not the major RCAHMS one ) but I can't find a ref for that . If anything was found under water it would be a portable .What would be good is to find something organic (preserved in the water ) with markings .
