Acoustics Time Dependent Study from a Frequency Domain Study

I am solving an acoustic problem with two different frequencies from continuous wave sources and need to track their interaction at a focal area.
The mesh requirement and time step requirement for a single time dependent study is extremely computationally intensive, given the ratio of acoustic wavelength to focal distance traveled, along with the higher frequencies involved. To combat this and make the computation time a little easier, I am solving two Frequency Domain studies, one for each frequency, then would like to run a Time Dependent study at the smaller focal area. However I am having trouble using the previously solved acoustic pressure solutions within the Time study, either as initial conditions or boundary conditions.
If someone could advise on the proper placement of 'acpr.p_t' (or similar) with 't' equation in the Pressure Acoustics, Transient physics section, it would be much appreciated. Or advise if my line of reason is incorrect. Thank you in advance.
Regards,
NCF
