I would be nice to have an exception on auto tiling

Some new windows go in automatic for the auto tiling but some of them i need not to go on that way, an example is my emoji picker, when i have the option "Enable Auto tilling" _(ON)_, my emoji picker go huge but i need it small, so an option to add exceptions for auto tilling, would be amazing, thanks for your amazing work!

PD: Just in case, this kind of windows is just a pop up window, so not having a tilling for this kind of windows is the goal (I think so).
