plot epoch_image for average of selection of channels

Hi all,

Does anybody know how it might be possible to look at epoch images over a
selection of channels, rather than a single channel? I'm analysing some EEG
data and hoping to average activity across a selection of visual
electrodes, and then look at the epoch image once it's sorted based on some
trial info, but doesn't seem straight forward (but i'm a relatively new
user, sorry!)

order = probeEpochs.events[:,2].argsort()
mne.viz.plot_epochs_image(probeEpochs, picks = range(53,61), colorbar =
True, cmap = 'interactive', order = order

this code will visualise the ordered epochs right, but will only do it for
the electrodes selected individually, rather than their average!

I know that mne.viz.plot_compare_evokeds will compare allow you to plot
ERPs averaged across channels, but can't seem to find a way of doing this
for epoch images

Any advice would be hugely appreciated!
