(How) can I (in project-gc !) identify caches hidden e.g. on the 25.11., regardless of year?

Question

When (for a challenge) I have to find at least N caches hidden on every day of year (regardless of year) and a specific day is still missing, I need to know, which caches have been hidden on that day (regardless of year).
How can I identify them online (e.g. using project-gc) and show them in the map?

I cannot do this offline (in GSAK), because I cannot load get so many caches (about 55.000 here in Austria) from geocaching.com into GSAK.

If project-gc does not contain such a function, is there a chance, that it will get it?

If you want to fill your placed date grid, you can use the Map Hidden Date function (https://project-gc.com/Tools/MapHiddenDate) to find the missing dates. There's no function to search for caches placed on a specific date (excluding year).

Thanks, but this is not what I need.
My Hidden Date matrix is already full, but I have to fill it a second or third time.
What can I use, to identify the needed caches?

Map Hidden Date will also work for further loops of hidden date matrix (if you are a paying member of Project-GC), I think.

Unfortunately Map Hidden Date does not work for further loops of hidden date matrix.
It says "You are not missing any hidden dates." :-(
