Need to make Aldeed Tabular use variable publish streams

I am using Aldeed Tabular to create data tables in a DIV element pane connected to file tree on another DIV element pane. When i click a folder on the file tree, it should change the contents of data table to that folder’s contents. I have created a way of publishing the contents each time to a new stream going by the parent folder ID. In the constructor to Tabular, we can give a pub: option that takes a publish stream name. But once we give a name, it becomes unchangeable. How can this problem be circumvented? There is no way i can know all the publish streams names because i do not know which folders the user clicks.

Any help is appreciated.
