Why would you need to duplicate the title ?

either you have them all in one title and you use the convert rows
or you have 2 separate titles ( a left and a right part maybe even combined in a multiview) and you just use a different line of your data source table for each title

There is always a way with some imagination
updating the DS will update the title

But i guess you mean by advance in the DS that you want to switch from A&B to C&D , in that case i woud opt for the two title multiview option , have a few shortcuts that advance your rows by 2 (and back in case off ;-) ) to go from AB to CD etc . One shortcut can do multiple commands at the "same time"
One can also structure your list accordingly like 2 boxer's stats per row etc.

if it is something you will use very often one could invest in making a custom title with some processing code behind it that read your data and processes it accordingly and externally controlled but that's different ball game. each way has its pros and cons


ps, name your title textfield names the same as your DS column headers, will save you time in configuring your title (autoconnect to the data)
