Can the prior information of Vp/Vs be added to the inversion process?

I thought this would reduce the non-uniqueness produced by the inversion, but I didn't find the corresponding code in the input file. I remember previous versions of the program had this feature.
Looking forward to reply, thank you

The current code does not support the direct utilization of prior information for Vp/Vs. However, you have the option to specify prior information for Vp and Vs independently. To achieve this, simply set the solve_anomaly option flag to 'T' in the parameter file. Subsequently, the velocity file specified as ref_vmod_in in the parameter file will serve as the reference model.

Fell free to ask any further questions.
