How do I download more than 1 PDF for brokerage statements' verifications?

Can you clarify the issue? 

I have info from 3 brokerage accounts. I entered all the data myself under the dividends and sales section. I was able to attach one PDF for one brokerage account, but when I wanted to attach another, the command was to delete the one I had already attached.

I am assuming that if I delete, it won't accompany my return. How do I add all 3 brokerage PDFs?
