[Tagging] adding sport detail to sport=multi using sport=x;multi

[Warin]

Hi,


I think I can add detail to the tag sport=multi where I can see what 
sport feature is there using bing satellite imagery.

As this would not always identify all the sports I would leave the tag 
'multi' but at the end of the tag

for example 'sport=soccer;multi' form a pitch visibly soccer from the 
imagery and previously tagged 'sport=multi'


This adds data and leaves the previous data there too.


Question 1. Is this ok?


---------------------------

I would do this using JOSM 'Download using API ..." and the query 
'sport=multi' to obtain the data.


Question 2. Is this method a 'mechanical edit'?!
