In the structural modeler, use the EDIM method to define the supports. Each support will have a start node and a stop node. Since the individual supports are not connected, they will all plot on top of each other in the structural modeler. However, when you include the file into a piping model, and connect the supports to the pipe with a CNODE, they will be positioned approporately. There is no need to modify the distance between the supports, they will move if you change the pipe lengths.
