If a straight length of tray is changed from one service type to another the shared parameter values are retained.
If i do the same thing with a fitting the shared parameter values are deleted, i wish these to be retained as well.
in addition to this, when multiple, joined straight lengths of tray are changed from one service to another they are all joined into 1 length, if i have them set to 3m as they will be bought and fitted this is working against me, not withstanding the fact that the tags and parameter values associated with all of the deleted content is lost as well.
