Use 30+ Wood plank images for wood floor render

Hi, I'm new to Substance 3D and work in the flooring industry. I'm wanting to take 30 or more individual wood plank bitmap images and feed them into substance 3d to create a wood floor render. I have discovered the tile floor generator but not sure how to go about inputing the 30+ bitmaps into the generator or if it's even possible. I believe I would need to use this in conjunction with the bitmap2material light filter to generate 3d maps of these bitmaps as well, and then feed them into the tile generator somehow. I tried doing this with Substance 3D sampler, but it appears their tiling generators only accept 4 materials (4 planks). Any help on how to do this or an alternate method would be appreciated.
