It would be great if you could easily filter hidden month caches in one filter. Say I wanted to see all caches hidden in 2001 in January (not a specific day). I would create 1 filter to see all caches hidden on Jan 2001 (without specifying a specific day).
I know you can get around this by creating 2 filters. One for any cache hidden on or after 01/01/2001, and another filter for everything on or before 31/01/2001.
The second process may be challenging for others to figure out. Might be cool to name the new filter “Jasmer (Month & Year)”.
This request would be helpful to those working on their Jasmer grids.
