Playgrounds and Play Structures

Hello everyone!
Got a complicated question. On the picture you can see that a climbing frame on a playground was submitted. But the whole playground as a wayspot itself already exists. As far as I know, single playground structures are not eligible, only the playground as a whole is.
Some qusetions:
What if...
a) The playground already exists as a wayspot and a playground structure is submitted? Reject? And if yes, what criterion?
b) One or more playground structures are already wayspots and someone nominates:
b1) The playground as a whole (Becuase this would be eligible, but the ineligible playground structures still exist ingame)
b2) Another playground structure (as far as I know it would be ineligible, but the submitter would be pretty confused if it was rejected because the other structures are wayspots)
Thanks for your answers :)

If the playground already exists, mark the individual equipment as a duplicate of it.
Likewise, in theory you could use this approach if someone has had an individual piece of equipment accepted. In the case of two or more already existing though, I'm not sure which you'd pick as the duplicate to be honest.
