gridding multiple lidar layers into multiple grid layers

The new script recording tool looks great!

I am trying to create intensity grids from lidar files created via photogrammetry of Mars Curiosity rover Navigation camera stereo 360 degree pans. The project's tools allow me to create csv files of xyzi data (the Navigation cameras are monochrome) that I then batch convert to lidar point clouds in Global Mapper. Next, I grid each layer's intensity values into separate gridded ortho images, then export them all with the same bounding box so that I can filter the images in Photoshop for removal of seams between "wedges".

Up to now, I've done this all interactively, selecting each layer (typically about 20 wedges for a 360 degree panorama) and gridding intensity, at 1 cm/pixel. With the script recording tool, I can create a script to process each image, but it appears they're all being placed into a single layer, which makes it impossible to edit them in photoshop individually. Is there a way to force the grids into separate layers rather than a single layer?

Al.so, so far I have to put in as much interactivity into the recording process as I do manually. Is there a way to create a script that increments to the next visible layer without having to paste in the layer's name?

Here is part of a script I'm running now on 19 navigation camera wedges (which, based on how long it's been running, must be putting all the wedges into a single layer):
