Have made a system for this exact thing that works a treat.....
Firstly make your main halyard long enough to go back to the traveller (or some other point aft)and fwd to the mast when the main is down.
Attach one of these to the point mentioned above

Now for steerage I used to tie the spinnaker sheets to the tiller and then clip together in front of the mast to control steerage.
30sec job to setup and pack up each time and worked a treat!!!
Snatch block was used instead of normal block as I used to run endless jib sheets through it for single handed sailing so the sheets wee always reachable from the steering position
