Remove initial clusters with less than 2 adjacent channels

Dear MNE team

I am using

  • MNE-Python version: 0.23.4
  • operating system: win 10

I have followed the tutorial:
Non-parametric 1 sample cluster statistic on single trial power — MNE 0.23.4 documentation
with the modification that I used my subjects’ tfrs for the cluster analysis.
As far as I read the documentation there is no way to control which clusters to be analyzed down the process chain.
In FieldTrip there is a parameter cfg.minnbchan which provides such control.
I mean once the clusters are formed based on a t-value, one should be able to discard it if no such cluster is found in an adjacent channel or two.
Has it not been implemented in MNE or I have to look for it somewhere else?
