Survey 123 question for you guys. I'm still exploring Collector and Survey 123 software platforms and I have run into the issue of Collector and its 3 relationships deep limitation. Now from my understanding, I can have a spatial aspect in survey 123 however I cant seem to find documentation on if I can have a relate to another spatial table in that software. Essentially I have a sign (spatial) and that sign can have multiple foundations (spatial) and each foundation can have multiple poles holding up the sign ( non-spatial) and the foundations and poles will need to have an inspection performed. This structure prevents me from using Collector. So would I be able to build out this structure in Survey 123 Assuming that I can load the pre-existing sign and foundation data into the blank schema? A rough diagram below
