TGuitar presets

TGuitar - Using the VOICER I changed the CHORD TYPEs to the appropriate M, m, 7, and dim for a major scale. Upon exiting I was prompted I could save a *.vstpreset file. Figuring I could reuse my changes, I saved it as DiatonicHarmony.vstpreset. But, I have found no way to load that preset file in standalone mode or when using TGuitar in Cubase (10.5 Pro). Am I correct in assuming that I can use the “save and exit” feature to create a reusable preset for TGuitar? And how is that accomplished.

Thanks for any help.
