I don't know if this will work or not as I haven't tried it, but seems sound enough. This is a snippet from the HTML Editor program that I found that puts a Back link on a page. So my thoughts on this are that you could create your landing page to be whererever (preferably an HTML page you create so you can easily insert the code needed) and then include this code below to give them an easy way to go "back" to where they came from.
Browsers: All
Additional information: This script 'jumps' you back one page. You can change the integer '1' to change how many pages back you want to jump.
-->
<a href="nojavascript...history.back(1)">Go Back</a>
I would think this could be altered like any other link to be a graphical button too by adding the appropriate code for that. Seems like a feasible solution maybe? Or just another idea at least to mull around and see how it looks/works.
