[Subsidies] Tool to delete documents in a subsidy attachment
Feature Request
Description
Subsidy objects (https://scipost.org/finances/subsidies/[subsisy_number]/) can have documents attached to them. Occasionally, the wrong attachment is added and 1) uses disk space, 2) pollutes the list of attached objects and 3) occupies a file name that should be used for a different document.
Please implement a button to delete the document itself, not only remove it from the list of attached objects.
Additional Information
The "update" tool in an object is not sufficient in some cases, as a document that is previously "deleted" with the current delete tool (so, just removed from the list but with the file remaining in the server) occupies a file name that we wish to use, and any new document with that file name would have an added hash even if we try to use the update tool.
