I get what you are saying, dthadmin, but I have the same question as saikrrishna.
I have already created a set of complex cb fields BEFORE I installed DT. I understand that the DT CB plug in creates additional cb fields (on a new tab) for the cross-connect, but surely I can somehow hack into the php or ini somewhere to just change the tab & field names DT accesses?
A future enhancement would be good to allow us to select the field names - I notice something like that for jomsocial somewhere I think...
