Hi, could you please try uninstall the ACT? Since you are already using the official Acoustic feature, you don't need that ACT anymore. If you have it loaded to the Harmonic Acoustic module it might interfere with the GUI. You can right click from tree to insert whatever definitions needed.
And yes you can define transfer admittance matrix, see help for details: https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v192/wb_sim/ds_acoustic_trans_admit_matrix.html?q=transfer%20admittance%20matrix
