Exporting one field from a series of subitems only

I need a simple export from Monday containing one column from a series of subitem columns.

It’s obviously possible to do this using the current Export to Excel feature, but that exports data in a layout that’s then difficult to easily access the data within it.

I just need to be able to export a simple flat table containing the value of a subitem column across numerous rows.

So the export just needs to look like this:
Subitem column name
Value 1
Value 2
Value3

Etc

Is that possible?
