Ongoing improvements of sub-mm- and mm-range interferometers and single-dishradiotelescopes are progressively allowing the detailed study of planetarynebulae (PNe) in molecular species other than 12CO and 13CO. We areimplementing a new set of tables for extending the capabilities of themorpho-kinematical modelling tool SHAPE+shapemol, so radiative transfer inmolecular species beyond 12CO and 13CO, namely C17O, C18O, HCN, HNC, CS, SiO,HCO+, and N2H+, are enabled under the Large Velocity Gradient approximationwith the ease of use of SHAPE. We present preliminary results on thesimultaneous analysis of a plethora of IRAM-30m and HERSCHEL/HIFI spectra, andNOEMA maps of different species in the pre-PN nebula M~1-92, which showinteresting features such as a previously undetected pair of polar, turbulent,high-temperature blobs, or a 17O/18O isotopic ratio of 1.7, which indicates theAGB should have turned C-rich, as opposed to the apparent nature of its O-richnebula.
