It would be useful to be able to specify whether or not to execute a lookup, based on an expression of the current data available.


For example, if an input field is NULL, I do not want the lookup to execute, as it will find multiple rows of data in the lookup (as it is a nullable field), so instead of returning an error or multiple rows (which are not relevant), there could be a condition/expression to determine whether to utilise the lookup (or whether or not to utilise the lookup result)
