change navigation button so it opens the new location in edit mode

My app has a button that redirects to a documents table, but I need that to be opened in edit mode. If I use the button, it automatically switches back to view mode. If I choose edit mode from the documents table it refreshes me to the top of the form. There is a checkbox I want people to use next to the documents table, but the only way they can get it to work is if they tab over 10 tabs to the documents table - making the button that takes them there immediately useless if they need to use the checkbox. The button uses a formula to make it work: "https://thefamilyplace.quickbase.com/nav/app/buf7b3sig/table/buf7b5kxp/action/dr?rid="& URLEncode( [Record ID#])&"&rl=dvb&page=21" how do I adjust this so it opens in edit mode? Thank you for your help!
