Ico,

How are the periods overlapping? I believe you will have to do it the "non-easy" way.

 - First, in order to get the all the period values, you will need to read the variable in with the default "cat" mode.

- Loop through the period variable to collect the indexes where the period values are unique.

You will have to decide which "unique" index to keep, and what to do with the data values that have the same two period values.
Do you just throw one of them away, or do you average the two, or what? If they are the same then no problem.

 - Index the array with this list of indexes to get the subset of the data you want:

  combined_var = var(iuniq,:,:,:,:)
