AnalogSingleChannelReader?

I have an application using an NI 9205 module configured for 16 differential analog channels.  I want to make it so that a user can select which paricular channel/s he/she wants to log data to TDMS.  It may only be one channel or could be multiple.  Do I need to use AnalogSingleChannelReader or AnalogMultiChannelReader for this?  I'm currently using multichannel reader and the application is writing all channels to the TDMS file.  However, I'm unsure what more I need to do if indeed AnalogMultiChannelReader is what I need to use.  Of course all of the channles that the user selects to log to TDMS need to be logged to a single TDMS file.
