Would it be possible to allow a "standard route segment" to be added to a planned route?

Flying out of Redhill I have a very limited number of departure options, which can be quite complex due to the surrounding airspace.  For example if going north I have to route via Ascot & Burnham through the Heathrow Class D or through Farnborough.  West, it's Solent.  East it's Luton or Southend. My standard segments can have up to a dozen waypoints, and more importantly, different altitudes on each leg to maintain.  It would be very useful to be able to set these routes up as standard segments which I could add to the start (or end) of a planned route. Others may find a frequent segment in the middle of flights, like (what used to be called) the Manchester LLC.
