2way FSi, Initialize with steady solution, Fluent, Transient Sturcural, System Coupli

Dear all, I am running a fully coupled Fluid-Structure Interaction in ANSYS Workbench 16.0.
First of all, I have to reach a steady solution to initialize my unsteady (transient) solution in Fluent.
In the similar project just in Fluent, I run steady then i change the solution type to unsteady and calculate. In these case, the steady solution becomes the initialization of my transient solution and the iteration continues as i start the transient solution.
But in Coupling the system, I encounter with this Note from ANSYS.
Note: System coupling overrides the fluent calculations.
By this notification, system coupling initialize my solution with the references values and the steady solution is gone and the transient solution starts with iteration 1.
First, I check to find a solution over the net, but unfortunately, I haven't found any solution till now.
Second, I try to Export Profile, to export all my data from steady solution and use it in my case to have the steady solution
I encounter with two problems here:
1) I have 9.5 m Structured mesh and my computer cannot export this enormous data and the fluent closed abnormally and suddenly
2) I tried with simple geometry and low mesh, as I read profile in new .cas the contours do not show any changes and seems that the profile doesn't work to use as initial condition
Third, I tried to record the script of system coupling, in order to omit the initialization and overriding of fluent calculations, but I didn't find any line by the name of "SOLUTION INITIALIZATION"
My main problem is that, i don't want system coupling to override my calculations.
PLZ and PLZ and more PLZ, If anyone knows anything or at least can suggest me a way to solve my problem, I would really appreciate it
