Ok...this is sounding better! I will tentatively take back some of my initial negativity!
If what is already there, stays there and stays on a first-come-first-serve basis...then this would be an enhancement. If balls are numbered and clearly marked...then should be fine.
Yes there will be some issues. But as it is you always see some clown moor up to the 'PRIVATE DIVE BOAT' balls that are there and then get chased away at sunset!
