How to resolve overlapped multiplets?

It is really easy to resolve overlapped multiplets. Imagine the below overlapped doublets:

where the peaks 1 and 3 correspond to one doublet and the other peaks (2 and 4) to the second doublet. First of all, divide the multiplet just by clicking on the red square of the multiplet label (to obtain two overlapped multiplets):

Next, double click on any of the multiplet boxes to launch the 'Multiplet Manager' dialog box. Once there, click on the 'Add multiplet peak' button (red square in the picture below). With this tool you can also remove peaks from the multiplet, by picking over a previously picked peak. Use this button to delete undesired peaks.

This will add a peak label with the multiplet name (A and B) over each peak, as you can see below:

Finally, hover the mouse over the multiplet box A, click and drag to the the label (B) of the peak 3, or vice versa, hover the mouse over the label of the peak 3, click and drag it to the multiplet box A (as it is shown in the picture below):

After that, the peak 3 will be a part of the multiplet A; (at this moment the multiplet A contains the peaks 1, 2 and 3):

Finally, do the same procedure with the peak 2 and the multiplet box B (click and drag the peak label to the multiplet box or vice versa), in order to include the peak 2 into the multiplet B:

As you can see in the picture above the multiplet A contains the peaks 1 and 3 and the multiplet B contains the peaks 2 and 4.
