After quite a few views I'm guessing nobody has an easy way to do this. Kind of what I thought.
Seems like a button to reload logos would be a good idea for the suggestion thread. I'll have to do that at some time.
Meanwhile I manually did them from the teams settings screen for all 6 levels of my league. Didn't take that long as there is a drop down to select teams. Could do each league from one screen so, less than an hour.
Thanks to all that took a peak even if there was no good answer
