Yes!  You can create your own folders or add samples to the default folders within the samples section of the plugin in your Finder/File Explorer window.  Drumslot will automatically strip silence and normalise your samples to -12db, the same as our pre-loaded samples. ​Drumslot is for one shot drums only so for best use we recommend only dropping in one shots/short files in 16bit and 44.1 kHz sample rate.
