How to temporarily change colour (highlight?) an object in Draw view?

Hello all; 

I am trying to (temporarily) change colour of parts in a drawing. Eg, if I have a pipe with 5 different spools; I'd like to make parts belonging to each spool to have a different color, or at least change some spools into a different color. 

I collected members, identified individual spools and tried things like these: 
      

        enhance $!mem
        -- does nothing
       
       highlight $!mem
       -- throws The HIGHLIGHT command is not available in Draw - consider using ENHANCE
       
         ENHANCE SOLE $!mem COL 2
         ENHANCE  $!mem COL 2
        -- both throws (47,62)   CP: Incomplete command line ENHANCE SOLE =201358652/605 COL 2^^

I used to achieve this via MARDRAFTING object from namespace 'aveva.marine.drafting' in drafting; eg 
mdraft = object MARDRAFTING ()
mdraft.elementColourSet   (!element, !yellow)

Please help...
