Cake and filling flavors catalog?

Hello everyone! I need your advice here. I’m re-arranging my cake and filling flavors ‘cause I use perishable fillings. It’s summer here so the cakes need to be chilled. Well, don’t need to explain what happens when you take a fondant cake out of the fridge at a room temperature of over 35ºC and 60 to 90% of humidity. So, as much as I like perishable fillings I need to change to non-perishable, otherwise I’ll loose my mind everytime I see a drop of water in my fondant cake (I suffered too much last summer because of that and I don’t want to go through that again) Anyway, I offer different sponge flavors on one side and different filling flavors on the other side, then the customer choose what they like the most (the sponge flavor and 2 different fillings). I was wondering if you guys offer a complete cake flavor (sponge and filling) – let’s say.. “Super chocolate” chocolate sponge and chocolate ganache (just an example)- or do you do like I do? and how many flavors do you offer?
Thank you! :)
