Individual soccer fields, baseball diamonds in park area
I am getting a large volume of submissions like this. The submission is a single soccer field of many and has a title and/or description that indicate there are multiples and they are numbered (ie, "Soccer Field 5"). There are usually some existing POI for others in the group (but not all of them). There is usually at least one existing POI nonspecifically for the entire park or cluster (ie, "<PARKNAME> Soccer Fields").
Very few of these individual nominations have a discernible marking or sign actually identifying them as "#5". If they do, it's usually just a small generic number attached somewhere to the goal net. I get the sense that in most cases it's the submitters themselves arbitrarily designating one or the other as "#5" (maybe based on the fact that they see 4 existing POIs, so this to them is #5).
As a general rule, I have been accepting individual nominations like this for single fields out of multiple, on the general principle that each individual soccer field is a separate location where people 'explore / exercise / socialize' so I'm giving them 4 because they meet all.
What's the best practice on these kinds of multiples? (Apologies if this has already been asked and answered)
