Hi Arno,

You mean that on can rise and lower the ballooner separate from the genoa ? Which mean that when the genoa is up and flying. 
On our Mango we used the ballooner on ocean crossings but we used the same halyard so needed to rise and bring them down together. 
I only can't figure out how the way you describe it. 

Best regards
Laurens
