Any way to redirect off a grid edit report?

I have a button that takes users to a grid edit report. Is there anyway to redirect them after they save? I tried &rdr and &NextURL. Rdr does as expected - redirects before the users have a chance to do anything. Next seems to do nothing? Perhaps it is only designed to work with the add record API? Any good workarounds?

var text Words = "Button Text";

var text Next = URLRoot() & "db/" & "bpxsuegfm?a=dbpage&pageID=4";

var text URL = URLRoot() & "db/br5abyum7?a=q&qid=10&nv=2&v0=" & [Record ID#] & "&v1=" & [Related SRM Project] & "&NextURL=" & URLEncode($Next);

"<a class='OpenAsPopup' data-height=850 data-width=800 href=" & $URL & ">" & $Words & "</a>"
