When I bottle beer (I have 3 x kegs for ales, I bottle mostly Belgian ales or Pils etc) I put the required sugar solution into an old (but sterilised) FV, then syphon the beer on top to mix.
The FV has a tap, to which I connect a little bottler (I think that's the name). I whizz through bottling by doing this. It's probably worth an investment if you are bottling lots.
Sorry, but can you clarify what you mean when you say "FV"?
I've only just started bottling mine after people were asking for some around Xmas. I drained a couple of cases of Badger beer's finest (courtesy of Costco), cleaned and sterilised the bottles, then relabelled them with personal labels. Might do my Dad some for Fathers day too.
Anyway, back to the topic, I found it a real pain syphoning beer, so I'm intrigued by your comment. Anything to simplify the process would be welcomed....
