[FieldTrip] Beamformer: different length of baseline and post baseline interval

I'm trying to beamform my MEG data by building a common filter including three conditions and a baseline for each condition. The baseline intervals have a duration of 500 ms. I was wondering if it is ok if the post-baseline data are longer than that (1000 - 2000 ms). Does it have any negative impact on the cross-spectral-density matrix and/or the common filter? Would that still be a valid operation to do or is it necessary that baseline and post baseline data have the same length?
Thank you for your comments.
