Hi Justin,
Thanks so much for reaching out!
Just to let you know, we are limited by our Support Policy in how much we can help with customizations, but I will try to point you in the right direction.
I’d recommend starting off by taking a look at our Themer’s Guide, which can show you which templates can be edited and copied in order to achieve the results that you are looking for.
You’ll want to use the code for the date picker in the month view and copy that into a copy of the Map View template into your theme.
Let me know how that goes and if you have any other questions on this topic!
Thanks,
Jaime
