Changing default display behaviour for Dataset

I have a function (whose code is in this site) to display Dataset in a more convenient way. To the extent that I never use the default one. I find myself constantly writing a code with a double entry:

allReportsWithDesc = 
  Query[Select[StringMatchQ[#Label, "[D0" ~~ ___] &], {"Label", 
     "Description"}]@dsNodes;
DisplayDatasetLive[allReportsWithDesc]

That is I suppress default output then use an alternative output.

I could write:

allReportsWithDesc = 
      Query[Select[StringMatchQ[#Label, "[D0" ~~ ___] &], {"Label", 
         "Description"}]@dsNodes;%//DisplayDatasetLive

I am wondering, however, if there was not a way to change the default display for Dataset to use DisplayDatasetLive. So I could write simply:

allReportsWithDesc = 
  Query[Select[StringMatchQ[#Label, "[D0" ~~ ___] &], {"Label", 
     "Description"}]@dsNodes

and the display would use DisplayDatasetLive (or some other function for that matter).

Look up $Post. – J. M.'s missing motivation Mar 09 '16 at 11:35
That's a useful functionality to know. So: $Post = If[Head[#] === Dataset, DisplayDatasetLive[#]] &; works like a charm. Thanks. – Trad Dog Mar 09 '16 at 11:44

You will want to actually use If[Head[#] === Dataset, DisplayDatasetLive[#], #] & so that other outputs are not affected. – J. M.'s missing motivation Mar 09 '16 at 11:48
Yes, that's correct. Thanks – Trad Dog Mar 09 '16 at 11:50
