Nearly all analysis tasks that produce climatology plots include a configuration option for specifying a list of seasons to plot:

# Months or seasons to plot (Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep,
# Oct, Nov, Dec, JFM, AMJ, JAS, OND, ANN)
seasons =  ['JFM', 'JAS', 'ANN']

Valid seasons include the three-letter abbreviations of each month (e.g. Jan), several 2- and 3-month seasons specified by consecutive first letters of each month name (JFM, AMJ, JAS, OND, ON, FM, DJF and JJA), and ANN for all 12 months.

If seasons other than these are needed, please post an issue on GitHub or contact the developers.
