Has anyone tried a late-season application of potassium on soybeans during grain fill?

Recently, I was speaking with an agronomist that suggested an application of potassium thiosulfate @ 1-2 gal rate during pod fill (R3ish) would be money well spent. Has anyone tried a late-season application with any success? Any other potassium products besides potassium thiosulfate?
