Portals: Dynamic field list
I have several equations that require evaluation. These equations have both different parameters (fields) and numbers of fields. While I can create a portal with all possible fields, it will be overlarge and many of the fields will not be relevant for a particular equation.
Is there a way of showing only the required fields relevant to a particular equation in this 1 portal. Obviously I will make the portal wide enough to accommodate the equation that has the widest set of fields/parameters.
