That is exactly what I ended up doing. 

But there is one strange thing. There are 75 CD sectors per
second (Ardour calls them frames). But in the location dialog,
times are shown in a format that divides a second in 30 units
(probably time code frames, FPS is set to 30, no drop).
Why is that ? If track start and end times must correspond to
CD sectors, that means that the times shown in that dialog are
not in fact exact. The actual markers probably are, since the
the track lengths as shown are not always equal to the the
difference of start and end. This is to be expected if the 
lenght is computed from start and end rounded to a CD sector
instead of as the difference of the displayed start and end.
But it leaves me wondering why a dialog showing CD track markers
doesn't use 75 units per seconds as its display format.
