BioNMR - How do I make ambiguous assignments in NMRView for Aria?

Hi,

I'm trying to learn NMRView.

If one has an overlapped peak (multiple possible assignments) and wishes to leave this peak as ambiguous for ARIA to decide on, how does one 'assign it' as ambiguous in NMRView?

I suspect either of the following:

1) Leave question marks in the assignment boxes (aka leave the peak unassigned aka do nothing)

Or

2) Make multiple tentative assignments for the peak (by using the ctrl button in the Peak Identification menu to highlight multiple possibilities, and then pressing 'Assign')

Or

3) Performing step 2) and then putting question marks beside each tentative assignment

Or

4) All of this is irrelavent because Aria automatically treats every peak, in cases where multiple assignments exist, as ambiguous, and then figures out, through iterative calculations, what the best assignments would be

I've read conflicting information on this question. You're advice would be tremendously appreciated.

Thank you for your time,

John
