Possibility to translate and make our own presets adding with a browse button.

I see presets are the same as iD editor. I know I can do my own preset with a fork like https://yopaseopor.github.io/deriviste/es/index.html
or I can try to make a patch with new items in the preset...but Could it be possible to add a browse button, then I find my preset file about an specific topic and then load into Deriviste?
