Files query field too big

having query field with a lot of images.
i think it is too big. especially the height.
can this be changed in any way?

i know it can be changed in the app.css
.k-dialog-box {
max-height: calc(75vh - 3rem);
but how can i make the changes permanent?

You can use a custom panel stylesheet:

easy when you know how.
