Schedule Later tool renaming attached files

I have consistently used HubSpot's Chrome Extension "Send Later" feature in my prospecting. My process is using a template and attaching a file and scheduling it to go out to my leads.

Since the change in the tool, where an outbox was introduced in the CRM versus Gmail drafts folder, I have noticed that the name of the evergreen prospect document that I attach to all scheduled emails is being RENAMED in the outbox. This results in my prospecting getting an attached file which is appended with a number. For example, I schedule one email with "Document.pdf" and the next email I schedule to a separate contact, although I attach the same file from Gmail, in the outbox and my prospect's inbox, the file name is "Document-1.pdf". This is unprofessional and use prohibitive of this otherwise amazing feature. 

Please prevent the auto-renaming of attached files by the schedule later tool.
