I also need the bars above the sometimes, but I have found that you can put any annotation above the lyrics just by putting it in brackets, so something like:
This [|] [Am]is [G]the [|] [C]way [|]
renders as:
| Am G | C |
This is the way
As you would expect. You can put other accents and things. In general anything with * in front of it is explicitly not a chord, but will go above the lyrics.
Hope this helps.
