Im wondering if there is any way to use wildcards in the columnList when calling snapshot on an RDataFrame? If not is there any plans to make this a feature?
For example, I only want to keep a small subset of the original branches but there are a lot of weights(~30) which I would like to keep but it would be time consuming to have to list them all manually.
Cheers!

Now have a question relating to using regex. I seem to be having trouble including any OR in the regex. For example:
^lep_pt$ works fine. As does: ^jet_pt$. However: ^lep_pt|jet_pt$ does not. Does anyone know of a reason for this? I have tried a toy example using TPRegexp and it matches fine, it just seems to be when using it in the RDataFrame.
