Contact Form 7 attachment in posts

Hey guys!

I have contact form 7 shortcode placed in every post, just because I need users to attach files (they sending me their CV to find a job).

Thus I have 300 posts and 100 files (CVs that I have recieved in my mailbox), and obviously

I can not guess which file(attached CV) relies to which post. This chaos…
Is there a way to add post ID or something so I can recognize to which specific post user has attached his file?

Thanks in advance, Hannah
