Change E-mail Subject

Hello, 

Hoping someone can help me. 

When I create a new shared link, via API, I get a newly generated (unique) link.

Works great - however, is it possible to edit the automated E-mail's subject?

Right now, when creating a new link, the admin gets an e-mail with the subject, that starts with: 

"You created a new file request for"...

I need to add something in the front of this subject (see bolded part), ie:

"[#11111]You created a new file request for"...

Is this possible? It's essential due to our ticketing system, which requires this or else a new ticket would be created everytime a client uploads / downloads files, and this is something we want to avoid.

Any help is apprecaited. 

Regards
