You could do this if you had a small and stable group of users by creating filter options for each one that activated and deactivated filterable conditions, but I’m sure that isn’t what you are going for. I have bumped up against this too in other ways. Perhaps Skuid could create a setting for “Deactivate existing filters on this field” option that would automatically deactivate current conditions when a filter option is chosen. Then you could could put a model condition set to filterable default on that restricts the OwnerId field and then when you make a choice with your filter, it would deactivate that condition.
