You will need to install a user script manager extension to install this script.
Handy script to help keep track of the various Mousehunt location timers. Timers are updated every minute automatically. You can also elect to have the script remind you each time of of the locations changes stage.
Now you can reduce the reminders to just the sublocations you want. With the remind checkbox on for a given location you will get reminders as follows
1) Master remind unchecked - no reminders for that area
2) Just the master remind checked -> all sublocation reminders
3) Master checked and one or more sublocations checked -> only get reminded for those sublocations
