I find it very frustrating and time-consuming that there is not the ability to export Organisation relationships in the same way that you can do for Individual relationships. If I need to clean Org relationships and I run a relationship query to group the records that I want to clean, it makes no sense at all to me that I then can't run an export that only exports the Org relationships that I want to clean.
To have to do a constituent query and export, and then manually delete the records that you don't need to clean is very time consuming, and doesn't always guarantee that the records that you want to clean are in the export.
