how to automate contour levels when paneling multiple frames

I am plotting multiple frames that compare two datasets on pressure levels.
I am looking for a way to automate the code to ensure the contours are the same between both datasets and their panels.
For example:
I have temperature that needs comparing at 40 pressure levels between two reanalysis datasets.
Obviously I could create an array of the max/min/spacing values that should be used on each pressure level, but with 40 levels, this can get extensive, and require the panels to be visually inspected first.
Is there a way to have panel 1 created, while assigning panel 2's contour resources to what panel 1 was set to?
Here is the paraphrased hardcoded (inefficient) code snippet for the plotting I am currently doing.
;Tavg(n_datasets, n_lev, n_lat, n_lon)
;mn = (/n_lev/);mx = (/n_lev/);sp = (/n_lev/)
do z = 0, n_lev-1
     resT@cnMinLevelValF = mn(z) resT@cnMaxLevelValF = mx(z) resT@cnLevelSpacingF = sp(z)
     plot(0) = gsn_csm_contour_map(wks, T_avg(0,z,:,:), resT) plot(1) = gsn_csm_contour_map(wks, T_avg(1,z,:,:), resT)
end do

Thanks in advance for all your time/efforts!
