Current functionality:

When we assign training to a user, and add an attachment, the following happens:

A folder is created in the attachments directory with the following format:
	employee_id_#####

A folder is created inside that folder with the following format:
	training_id_####


So if I am adding an attachment for employee id 45 for training id 101 it would look like this:

	employee_id_45\training_id_101\attachment_name.pdf

The filename of the attachment is changed:

	if the original filename is "certificate.jpg" then the destination filename is:
	
	certificate<timestamp>.jpg

The timestamp is in the format of: YYYYMM-DDHH-MMSS

so the resulting filename is certificate_202502-2812-1200.jpg
