[Feature]: Support inline wildcard in file wildcard

Feature description

I would like support for something like this in a wildcard file:

forest, cabin, river, {morning|evening}, {rainy|misty}, {secluded|quiet}, {cozy|relaxing}
forest, trees, {morning|evening}, {foggy|misty}, {tranquil|serene}, {mysterious|ethereal}

This would allow for more flexibility in dynamic prompting, since as of right now, any '|' in a file wildcard will be assumed to be for using multiple choices per line, instead of using one choice per line, but with inline wildcard from within that line.
