This is related to a Rollup field. This can allow you to tick 'Only include linked records from the Properties table that meet certain conditions'.
Is it possible to do the value of the condition, based on a value in the current record? I want to do the below:
Where (Linked Record) RoomId = (CurrentRow).RoomId.
It seems to only take static values, which in this case does not make sense. If not possible, are there any possible workarounds?
