[Tagging] tagging seasonal sports

[Warin]

Hi,

Where one sport is played in winter (eg soccer) and another in played in 
summer (e.g. soccer) ... I have two methods

sport=cricket;soccer ... and thus lose the seasonal information

OR

tag each pitch;
the cricket pitch is usually circular and tagged 
sport=cricket,seasonal=summer
the soccer pitch is rectangular, overlays the cricket pitch and is tagged
sport=soccer, seasonal=summer

BUT
what to do if I'm lazy or the pitches are indistinct and a only have one 
way/pitch to tag .. but want to include the seasonal information? Even 
opening_hours if there are known dates cannot be used on dual tag for 
the same way.


Ideas?
