Hm, I tried that before I posted and didn't get good results... but I'll give it another try.
I got spreads but I didn't find specifically relationship spreads (I did the search with "relationship spread" in quotes.)
Edited to add:
I did a little more digging with the search results since I had a little extra time to READ instead of SKIM the results.
I found a few spreads I may be able to use.
Thank you... sorry for the unnecessary post.
