Include wild cards in save folder structure or file name

[sjdevries]

Firstly, thank you for this really awesome plugin.

An enhancement feature that I think would be pretty awesome for combinatorial generation would be to save the images in directories based on the wild cards in the prompts.

For example if you used __jumbo/people/nationalities/australasia__ in the prompt, and generated batches of 4. It would put 4 images in each of the following folders:
Australian/
New Zealander/
Norfolk Islander/

For handling multiple wild cards you could have the option of character delimited appending of the wild card values, or using sub-folders.

Example:

__jumbo/people/nationalities/australasia__
__jumbo/appearance/haircolour__

Using " - " as the delimiter:
Australian - Auburn/
Australian - Black/
Australian - Blond/ ...

Using sub-folders:
Australian/Auburn/
Australian/Black/
Australian/Blond/ ...

Another nice option would be a batch name for that entire combinatorial batch. So you could make a batch named "landscapes" with __seasons__ and __terrain__ wild cards to generate images sorted appropriately:
landscapes/summer/mountains/image#
landscapes/winter/hills/image#
landscapes/fall/forest/image#
... etc.

I'm not certain how difficult it is to add patterns to the save options. Something like:
[batch_name] - base folder for the batch to go into
[wild_cards] - makes sub folders for wild cards in order of appearance in prompt
[wild_cards_delimited] - makes folders with wild cards in order of appearance separated by a delimiter

I feel like this would be more useful than the current options for adding the entire prompt or a part of it to the image name or folder name.

I think this might be out of scope for the extension. DP focuses on prompt manipulation, not determining where generated images are placed. If I understand your request correctly, another extension would be better suited to dynamically determining where to store outputs, perhaps in cooperation with dynamicprompts through global variables (see #431)
