Preserve file name when exporting files with forward slash in name

Is there a way to preserve the file name when exporting a frame using the forward slashes in the name?

I am exporting several hundred banners and am using the forward slash to have each frame categorized into folders when exporting

My files are currently named as follows:

…and so on.

I want Figma to open new folders and subfolders when exporting, but I also want to preserve the full file name
eg: Client/Wk5/Desktop_3000x1200.JPG

Is there a way to preserve the file names and get the benefit of the automatic folder structure?

At the moment, I am having to choose between separating hundreds of assets manually into folders, or having the folders but losing the file naming.
