Dependencies small to big segmentation

Is it possible to have dependencies on tiers but the big one segment is dependent with small one segment and not small one dependant on big one.
For exemple one tier of word segmentation and i want to have syntactic component on another tier but with the same segmentation of 1, 2 or 3 words for example.

No this is not possible.
Preparations for that are already in the file format as “reference links” that allow to group (references to) multiple annotations on another tier, but since there isn’t a way yet to create and visualize them in the user interface, it is not yet possible for users to make use of this.
