Is it possible to change the location of the .PeaktoC1HigreshPreview folder, which contains the high-resolution previews from the C1 catalog?

My Peakto database is on my SSD at /Volumes/SSD/Photos/Peakto, but it generates these files (via C1) in /Users/Fred/Pictures/.PeaktoC1HigreshPreview...

Thanks in advance.
