IPUMS-CPS does not currently make all of the Outgoing Rotation Group questions available as part of the non-March Samples. However, IPUMS-CPS is working on expanding the availability of these variables as a part of the increase in basic monthly samples and variables. In the meantime, it is possible to merge data from the non-March NBER basic monthly data files onto the corresponding IPUMS-CPS samples using a sequential merge. See this question for more detail.
I hope this helps.
