Retrologue vstpreset files Drag and Drop?

I have a Retrologue vstpreset file and I can’t seem to Drag and Drop the file onto the Retrologue. Is this not possible? I was hoping to take the vstpreset file and just drop it on top of the Retrologue GUI and the Retrologue would pick up the patch… but it doesn’t seem to work… I’ve hovered around the Load Preset area and all I get is the circle with a line thru it…
Thanks,
