Saving slices with a fixed prefix of choice

Question

[Edit: I just discovered a wonderful Batch Rename option in Bridge, so this is a good workaround for me]
I have a file with many slices. The file has several layer comps and they just change the color cast with hue-sat adjustment, so they are named "green", "yellow", "red", etc. I must save the slices for each layer comp into globally unique named files, because later they will be mixed all together on a web site. Ideally, the names would be like this:
green_slice1.jpg
green_slice2.jpg
yellow_slice1.jpg
yellow_slice2.jpg
where "green" and "yellow" are after layer comp name and the rest is slice name.
I looked into the "Other" Output Settings options, File Naming section but there seems to be no option for layer comp prefix or any user invented prefix that would enable me to save them to the same folder and not override (I wouldn't mind typing manually the color name, but there is no option to "use an arbitrary word of your choice"). So it looks like the only solution is to save each layer comp to a separate document and then use the Save for Web and Devices in each document with the doc. Name filename prefix. But I am asking here just in case that maybe there is some workaround, because making copies of such files is a bit artificial, just for saving and then delete and a bit of waste of time.

Answer 1

There are Text bullets which would allow you to start with "Part" but you can't then combine that with numbered lists in the following indent of the line.
I can't imagine that it will be such a burden to have to label this level manually, or simply omit the redundent "Part". The division should be obvious from the context.
It is something I find totally redundant in tutorials when people repeatedly label things Step 1, Step 2, Step 3 etc. They are just 1, 2, 3 etc and obviously steps, or whatever else you want to describe them.
Imagine adding "Point" in front of every • bullet. "Dash" in front of every -.
