According to the latest p4v documentation (https://www.perforce.com/perforce/doc.current/manuals/p4v/p4v.pdf) I should be able to unload a task stream from p4v by right clicking the stream and selecting unload. This option never appears for me. Is there some condition that must be met for this option to appear? Thanks!
Edit: I am running p4v 2018.2/1687764
