Where do these pressure values come from? If you have run an Ansys CFD solver, such as Fluent or CFX, you should be able to transfer all time points by linking the fluid Solution cell to the structural Setup cell:
Are the locations the same for each file or are you applying by "direct assignment" which is by node/element ID (requires same mesh as in structural as well as fluid module)? If so, you can make one file in Excel by making the pressure data in each file as a new column in the singular file. I guess this still doesn't help with setting the rows in the imported load though.
I'm not sure if there is a limit to the GUI, but you could try a Mechanical python script to create the rows, If the GUI has a limit, it would have to be done by APDL commands.
