form tuples based on the file name regex from different directories

[freimannk]

Is there anyway to join channels / form tuples based on the file name regex from different directories?
For example, I have 3 directories:

data/path1 and files x_variants_51459_52468_results.parquet, x_variants_0_1009_results.parquet ….

data/path2 and files y_variants_51459_52468_results.parquet, y_variants_0_1009_results.parquet …

data/path3 and files z_variants_51459_52468_results.parquet, x_variants_0_1009_results.parquet …

I would like to form tuples based on regex pattern inside file names.

For example: [x_variants_51459_52468_results.parquet, y_variants_51459_52468_results.parquet, z_variants_51459_52468_results.parquet]
I have lots of files so I would like to not specify the exact number pattern.
I would like to use the regex pattern pairing, somehow like this:
'/data/**/*{-can I do regex, like file.simpleName.find( ‘\d+\d+’)?-}_results.parquet’?
