You can create and remove control points according to table definitions using:

 Table.query("INSERT INTO Objects() (<propertynames>)  SELECT <propertynames> FROM $1", table)  

as described here where you replace <propertynames> with those needed for Control Points. To see what properties those are, just open a Properties table from the Properties panel for a control point or look at the list of properties in the documentation.

Similarly you can also remove them with a similar sql clause : "DELETE FROM Objects() WHERE...."

The place to do this is probably best within the OnSet of a Parameter (since that fires before the model is reset). The parameter could allow you to switch between tables defining the control points you want to use.

There could be complications if, for example, your dynamically added/removed control points are connected to stations/agvs - you may need to account for that in your code.

If you just need to relocate control points then you can use the UPDATE sql clause and you can create your scenarios by moving them manually and then recording the properties tables that you then switch to via the parameters.
