Adobe DC. Hyperlinking attachments so when they close the parent documents remains open.

I am preparing a legal brief and want to attach supporting excerpts to the brief as separate pdfs that can be hyperlinked. The pdfs attach and I can hyperlink them. OK so far. The problem is opening the hyperlink and then returning to the parent document when the link is closed. When the hyperlink is closed only the attachment remains;the parent document closes and goes away. Very frustrating.I have a work-around by combining all pdf files and hyperlinking to each attachment. However many attachments are multiple pages so if the reader begins scrolling, then how does he get back? Alt + left arrow is too cumbersome and confusing. We put return links on the bottom of each page of the attachments--but really? This is a hokey way to do things. Thanks. Russell.
