Warning for overlapping sessions

[ZacWarham]

It is possible to create two sessions in the same location that overlap each other (see location 014 in the image). It would be beneficial to show a warning somewhere if this occurs. I suggest warning as opposed to error in case there is a use case for this I am not aware of?

Some thoughts on a possible location to show the warning

• when editing a conflicting session
• the day view showing all sessions booked that day
• when running the Predict Usage option

Turns out we have one use for something like this already. We indicate a day the centre is closed with a tag on a whole day session but some programs are allowed access so they have a session just for them.
