Condition on basic model to determine if Id of row is in grouping of aggregate model?

No problem, Rob. Thanks you guys for the feedback on my question. In most cases this would work and gets us almost there by showing all tasks based on AccountId. The only part this doesn’t work for is the fact that Opportunities can be related to another Account through a lookup field on the Opportunity from what we have built. In such a case an Account would technically be related to an Opportunity if they were just in the lookup field alone and we’d want to see that Opportunities tasks in the lists too. Is this possible with Skuid conditions?
