It's "merge selection" checkmark, and i added that on 10th March, so it should be in that 11th March build.
If it's not checked, the action is indeed applied for each entry. About quotes it's "normal", "don't quote" seems to have another meaning internally. It's quite easy to strip them from an arexx script (more or less with the rexx line i gave earlier).
Command evaluation backquotes seem to work here. If i just set "echo `c:requestfile`", it just works fine and prints what i selected.
