Yes, we can
Try to add something like
<font color="#3399FF"><b><a href="
<script>
var loca = "_MOVIE_LINK1_";
loca = loca.substring(0, loca.lastIndexOf("/"));
document.write(loca);
</script>
"> Location</a></b></font>
to the _Detail.htm in Custom2.
The script code extracts the filepath and writes a link to the location that you can open.
I did not have tested it but it should work.
If you don't want to have the link just plain text then remove the href part.
