Version 2.1 of PP has been modified to allow for plotting of transmission losses, derived from the OASP transfer functions. This also allows for extreme near-field transmission loss computations with the full exact Bessel function integration (OASP option f).
Choosing field 13 brings up the transmission loss submenu,, allowing selction of plot formats, currently supporting TL vs range, depth or frequency, depth-averaged TL, or depth-range contours:
